Science Log for Week Feb. 4 to Feb 8, 2013
One of the main components of the CIRCULATORY SYSTEM is the blood. Blood is composed of 4 parts:
1. Red Blood Cells (RBC): The primary function of red
blood cells is to transport oxygen throughout the body
2. White Blood Cells (WBC): White Blood Cells fight disease
3. Platelets: Platelets, along with other proteins, form blood clots. When blood is exposed to air,
platelets become sticky and form internal and external “scabs” to catch the blood cells
and plasma, thereby stopping bleeding.
4. Plasma: Blood is composed of plasma, which is about ninety percent water. Plasma serves as the
main transportation component in the body since it is the liquid part of blood.
For this weeks posting write about the blood and how it helps us transport oxygen and nutrients throughout our bodies. You can also mention any concerns about blood or any blood disease.

It is pretty interesting how our the circulatory system works. The difference between the circulatory and respiratory systems is the circulatory system carries blood throughout the body and the respiratory system is the way the body exchanges gases between the blood and air. The two systems work together in that when the heart beats, oxygen deprived blood exits the heart via the pulmonary artery. Blood travels down the pulmonary artery to the lungs where it enters a capillary system surrounding the aveloi in the lungs. It is here where excess carbon dioxide exits the blood and oxygen enters. The oxygen rich blood now returns to the heart where it is pumped through out the whole body.
ReplyDeleteAwesome explanation Haimadou! Great work
DeleteIts very impresive that we have so much going on in our body . Everthing starts out with oxygen enters our mouth travels through the body and enters the heart.Blood cells have a job to varry waste to thr kidneys and later on to be digested.
ReplyDeleteInteresting scope Henry! Yes the blood does retrieve waste which flows through our kidneys to be filtered and excreted through our urinary tract in our urine. This week we will cover more or this. Keep up the great work Henry.
DeleteHi My name is Bianca Franklin and I have learned a lot in Science this school year.Peace My Babies <3
ReplyDelete?????? Hello Bianca... looking forward to reading your posts
Deletei thin the circulatory system is interesting.i learned that the white blood cell transport oxygen throughout the body.I also learned that the white cells help fight disease.
ReplyDeleteDavontae, just a small correction. Red Blood Cell (RBC) are the blood cells that transports oxygen and the White Blood Cell (WBC)are the ones responsible in the fight against diseases and foreign bodies in our body. WBC are directly related to the immune response.
DeleteI agree with you Mr. Rosado
Deleteibrahim diallo
The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, oxygen and other gases, and hormones to and from cells. Without the circulatory system, the body would not be able to fight disease or maintain a stable internal environment — such as proper temperature and pH — known as homeostasis.
ReplyDeleteTHE HEART
The heart pumps oxygenated blood to the body and deoxygenated blood to the lungs. In the human heart there is one atrium and one ventricle for each circulation, and with both a systemic and a pulmonary circulation there are four chambers in total: left atrium, left ventricle, right atrium and right ventricle. The right atrium is the upper chamber of the right side of the heart. The blood that is returned to the right atrium is oxygenation (poor in oxygen) and passed into the right ventricle to be pumped through the pulmonary artery to the lungs for re-oxygenation and removal of carbon dioxide. The left atrium receives newly oxygenated blood from the lungs as well as the pulmonary vein which is passed into the strong left ventricle to be pumped through the aorta to the different
organs of the body.the main function of the blood
1. plasma: About 55% of whole blood is blood plasma, a fluid that is the blood's liquid medium, which by itself is straw-yellow in color. The blood plasma volume totals of 2.7-3.0 litres in an average human. It is essentially an aqueous solution containing 92% water, 8% blood plasma proteins, and trace amounts of other materials. Plasma circulates dissolved nutrients, such as, glucose, amino acids and fatty acids (dissolved in the blood or bound to plasma proteins), and removes waste products, such as, carbon dioxide, urea and lactic acid.
2. red blood cells (erythrocytes): These contain hemoglobin, an iron-containing protein, which facilitates transportation of oxygen by reversibly binding to this respiratory gas and greatly increasing its solubility in blood.
3. White blood cells: White blood cells are part of the immune system; they destroy and remove old or aberrant cells and cellular debris, as well as attack infectious agents (pathogens) and foreign substances
4. Platelets: Platelets are responsible for blood clotting (coagulation). They change fibrinogen into fibrin. This fibrin creates a mesh onto which red blood cells collect and clot, which then stops more blood from leaving the body and also helps to prevent bacteria from entering the body.
even though i do not particularly like the C system this is very interesting to know.
DeleteAwesome work! Keep up the great work Elhadj Faye.
DeleteThe circulatory system involves several things. One of them is blood. You get darker blood when the arteries are cut and lighter blood when we cut our veins. It is an old myth that when your blood hits the oxygen it turns red but inside your body it started off blue. I believe this partially and would like to know the real answer. Even though the circulatory system is interesting i do not really enjoy it as much as others. Anthony Lopez 733
ReplyDeleteI would like to know if that is a myth as well.
DeleteSmailyn Nicasio 733
I also, would like to know if the myth is true or false
DeleteKenneth Cosme 733
Blood that is high in oxygen is a darker shade of red; this is present in veins, and can be seen during blood donation and when venous blood samples are taken.
DeleteHOPE THIS NEXT STATEMENT WILL ANSWER YOUR MYTH:
Veins close to the surface of the skin appear blue for a variety of reasons. However, the factors that contribute to this alteration of color perception are related to the light-scattering properties of the skin and the processing of visual input by the visual cortex, rather than the actual color of the venous blood. THERE IS NO BLUE BLOOD !!
Correction: BLOOD THAT IS HIGH IN OXYGEN RUNS THROUGH OUR ARTERIES ! ARTERIES .... ARTERIES ..... ARTERIES
DeleteI Think The Circulatory System Is Very Very Interesting. Circulatory System Is An Organ System That Passes Nutrients (Such As Amino Acids, Electrolytes And Lymph), Gases, Hormones, Blood Cells, Etc. To And From Cells In The Body To Help Fight Diseases Which I Think Is So AWESOME! . -Jolene Cortez 7-731
ReplyDeleteI feel the same way about the circulatory system
DeleteKenneth Cosme 733
I am glad you feel this way. The circulatory system moves nutrients and oxygen and retrieves waste products to get eliminated by the kidneys.
DeleteThe Circulatory system is my third favorite system. The circulatory system consists of several things but I am going to be talking about blood. Blood flows throughout our bodies through our veins and arteries. Also, Blood carries oxygen and nutrients to your body's tissues. Adittionaly, blood takes carbon dioxide and waste products away from the tissues. Finally, blood is needed to sustain life and promote the health of all the body's tissues.
ReplyDeleteKenneth Cosme 733
Like many say "life is in the BLOOD".
DeleteThe Circulatory System is an important part of our body. The Circulatory System is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all of your body cells.
ReplyDeleteYes Abigail, like you said "It is an amazing highway that travels through your entire body connecting all of your body cells".
DeleteThe circulatory system consisting of the heart, blood vessels, and blood that circulates blood throughout the body, delivers nutrients and other essential materials to cells, and removes waste products. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which returns excess filtered blood plasma from the interstitial fluid as lymph. The cardiovascular system and the lymphatic system collectively make up the circulatory system.

DeleteGreat post Ibrahim!!
DeleteThis week we learned about Blood vessels. this topic was very interesting. We learned that the function of arteries is that it carries blood away from the heart. The capillaries function is that it joins the arteries and veins. The veins carries blood back to the heart. We also learned the definition of blood pressure, which is the pressure of blood against the walls of the arteries and other blood vessels.
ReplyDeleteThe first number measures how high your blood pressure is. The second number measures how many beats your heart is beating per minute. For homework i learned some healthy habits on how to prevent cardiovascular diseases. Some ways are: don't use salt, no fried foods, exercise, est fruits, eat vegetables, try to stay under weight, and get proper rest. I also found out the definition of blood vessels. The definition is any of the tubes in the body through which the blood flows. Any artery, vein, or capillary.
This was a very interesting topic and I would love to do it again. There were many more things we learned about on this topic and it was very interesting.
Today's society being a stress related environment, people with high blood pressure is on the rise!!!
DeleteDuring this week we learned that one of the main components of the CIRCULATORY SYSTEM is the blood.Blood is made of 4 parts.The 4 parts of the blood is red blood cells,white Blood Cells, Platelets,Plasma blood.The blood helps us transport oxygen and nutrients throughout our bodies.
ReplyDeleteYou got Yamileth !
Deleteblood is in us.there are four basic components in the blood. Red blood cells, white blood cells, platelets and plasma. they all do very important parts.
ReplyDeleteThat's correct Kedwin!
Deletethis week we learned that blood brings Oxygen to our heart.that goes through the veins.the four main components of blood are red blood cells,white blood cells,platelets,and plasma.With out our blood we would all not be alive.all the steps taken are just like a river.
ReplyDeletein heart our heart there is a proccess. In the beggenging the air is pushed into the heart. So the good air is pushed out the heart to go through the body for everypart get air. thought some of the air goe back to the lungs and come out of the body. THat is carbon dioxide. Also which is the most impotant system in the body
ReplyDelete.
Blood will carry the oxygen thru our bodies via the arteries, capillaries and then take blood low in oxygen back to the heart for more oxygen
Deleteotherwise i do enjoy this topic but i will like to learn about the nervous system. Because i want to know how our body reacts and how do we get spasms.also do a nervous system have anything to do with chest pains.
ReplyDeleteI never really thought about the nervous system causing spasms or other body problems, now that I think of it, it makes me wonder. Does that mean that the nervous system can be really sensitive that it can make us jolt or is it from birth defects or genetics? It can even be all three combined! That doesn't make me feel too happy about that, though...
DeleteThis weeks topic was pretty cool! I always wondered how scabs were made and why there we so much fewer white cells than red cells. I also know its would be a pretty hard job to make all these blood cells if they were mandatory. I never really thought about how its good to have blood in our bodies yet some people are scared of blood. They're just scared of themselves. The body is awesome in so many ways and science proves why! Narwhale AWAY!
ReplyDeleteYour heart is really a muscle. It's located a little to the left of the middle of your chest, and it's about the size of your fist. There are lots of muscles all over your body in your arms, in your legs, in your back, even in your behind.
ReplyDeleteBut the heart muscle is special because of what it does. The heart sends blood around your body. The blood provides your body with the oxygen and nutrients it needs. It also carries away waste.

ReplyDeleteThis week in science class i learned about Blood Vessels I'll tell you about the Blood Vessels there are three varieties of blood vessels: arteries, veins, and capillaries. During blood circulation, the arteries carry blood away from the heart. The capillaries connect the arteries to veins. Finally, the veins carry the blood back to the heart.
DeleteIf you took all of the blood vessels out of an average child, and laid them out in one line, the line would be over 60,000 miles long! An adult's vessels would be closer to 100,000 miles long! I hpoe you like it and ill blog again later ;)
Great information Emmaline .... thats a lot of vessels !!! who could imagen something like this .... thanks for the info.
DeleteLast week we learned about Blood Vessels ,I know that Blood Vessels are the blood vessels are the part of the circulatory system that transports blood throughout the body. There are three major types of blood vessels: the arteries, which carry the blood away from the heart; the capillaries, which enable the actual exchange of water and chemicals between the blood and the tissues; and the veins, which carry blood from the capillaries back toward the heart.
ReplyDeleteAwesome Destiny! keep up the good work !

ReplyDeleteThe human circulatory system has three main parts:
ReplyDelete(1) the heart
(2) the blood vessels
(3) the blood
A watery fluid called lymph, and the vessels that carry it, are sometimes considered a part of the circulatory system
Thats right Anthony! keep up the great work ...
DeleteThis weeks lesson was good.I learned about how the circulatoy system has blood vesels witch helps the blood travel throw out the body.There are many types of blood vessels such as the arteries it keeps the blood away from the heart.Also i found out about the capillaries exchanges water chemicals between the blood tissues,and the vains that carry blood tords the heart
ReplyDeleteyou are on a science roll!!! keep it up Alpha !
DeleteFor The Past Week In Science We Been Learning About The Body Par Of An Average Human How Your Blood Moves Around Your Body . On average, your body has about 5 liters of blood continually traveling through it by way of the circulatory system. The heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey.
ReplyDeleteThe body's circulatory system really has three distinct parts: pulmonary circulation, coronary circulation, and systemic circulation. Or, the lungs the heart and the rest of the system (systemic). Each part must be working independently in order for them to all work together.
Yes Darlene, and all 3 parts are critical and important.
DeleteToday this week we learned about the disgestive system an how in functions. The small intestines are where the nutrients are absorbed. The large intestines where water is absorbed. The kidney is where are the organs that filter the blood, Also, the ureter is a tube that carries urin from each kidney to the bladder. In addition, the nephron is where tiny filtering units of the kidney and the bladder is where our wter goes so we can take out the urine.
ReplyDeleteYou got it down Jeffrey ... keep up the awesome work! You are moving uptown !
DeleteThis weeks lesson was cool.Ilearned about red blood cells and how they affect the body.The red blood cell is located in the the marro, red blood cells have 120 day to live.I also found out aboutthe 3 important orgains in our body witch are heart,liver,and kidney.That was what i learned this week great lesson.
ReplyDeleteYes Alpha, like every cell in our body .. they all have a place of origin. Red Blood Cells (RBC) are formed in the bone marrow like you mentioned.
DeleteThis week lesson about the topic in curculatory system about blood cells.One blood cell is the red blood cell, that takes oxigan goes throught the body.Another is whight blood cells, they fight of sicknesses and germs and desises.Lastly is the platelets they stop blood clocks,for exsample when u cut your self the body idmeadetly creates a scab to protect the skinn cool !!!! GREAT LESSION I LEARNED A LOT.
ReplyDeleteThis week in class we were taking notes on what the circulatory system was and how it works in the humans body
ReplyDeletethis year was a great year i think we should end it on a great leve...SYCH
