Circulatory System

One of human body system that students learn in this Unit of Inquiry “Who We Are” is Circulatory System. It is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis.

Students learn how blood circulates from and to the heart or to our body by role playing (on a giant heart poster) as the blood that runs through the four chambers of heart, such as right atrium, right ventricle, left atrium, and left ventricle. They need to wear red and blue t-shirt to show different roles and functions of the blood which passing through the right chamber (the blue part) and the left chamber (the red part). They are very excited!
