Question

3. The circulatory system is one of the several systems of the human body that
work together to keep a person healthy. The main function of the circulatory
system is to carry blood throughout our bodies and transports blood to and from
the heart, and carries oxygen and nutrients to every cell in the body. The
circulatory system is connected throughout the body by two main parts of the
circulatory system, the heart and blood vessels. The heart contains a total of four
chambers. The left and right atria are the chambers of the heart that receive
blood into the heart. The atria are located in the upper part of the heart. The
ventricles are located in the bottom part of the heart and pump blood out of the
heart. Heart valves separate the four chambers of the heart. The blood vessels
include arteries, veins, and capillaries The arteries carry blood away from the
heart. The arteries are the thickest of the blood vessels. The blood is enriched
with oxygen as it is sent through a large artery called the aorta, to the rest of the
body. The veins of the circulatory system carry blood back to the heart. The
capillaries are tiny blood vessels that carry blood between the arteries and the
veins. The capillaries deliver nutrients and oxygen to the cells in the body. 3a. The

A. Carry blood throughout a person's body
