Hello!

Today in class we learned about the structure and function of the circulatory system.

Structure: heart, blood vessels (such as veins, capillaries and arteries) and blood (white blood cells, plasma and red blood cells)

Function: to bring oxygen and nutrients to the cells in your body and to help get waste out of the body

circulatory system

We also learned that the blood first gets pumped from the heart to the lungs, then returns to the heart and gets pumped out towards the rest of the body. We will make a model of this tomorrow.

Tonight’s homework: read, highlight and annotate the article attached Getting to Know the Circulatory System
