Understanding how all organ systems work together, describe and present evidence of what would happen if the relationship between these systems are broken. What happens to homeostasis (balance)? Can the disease state of one organ system bring down the health of another organ system? Blog away!

Bilingual Science Log: Semana de 11 Feb. al 15 Feb. 2013

Comentar sobre lo que aprendio sobre el sistema circulatorio durante la semana.

Shout out to Ariel Molina-Gameos (733) for her talent!

Ariel's talent will be displayed in my room! Thanks Ariel for bringing color and life into our classroom.

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.

Congratulations Ahsyana Wright for your special project

Wow, I am very proud of the project Ahsyana Wright from 733 turned in for extra credit. I just can't take my eyes off it and show it to my colleagues and school staff. You did an awesome job! Take a look at her design/model and interpretation of an active volcano during the era of the dinosaurs.

Science Log for Week Jan. 27 to Feb. 1, 2013

This week we covered the Circulatory System and its parts. We analyzed the flow of blood through the heart and it's distribution throughout the human body. The distribution of blood is made possible through the use of a complicated, but effective network of blood vessels (Arteries, Veins, and Capillaries). We also mentioned various disease states of the circulatory system, especially of the heart. This week post your comment about this topic, or any related scientific contribution. Blog On!
