Cardiovascular System

The cardiovascular system pumps the blood throughout the body.  One function of the blood is to deliver and remove substances from the body.  The red blood cells transport oxygen to the cells of the body.  The white blood cells take care of toxins and inflammation in the body.  The blood also protects the body by clotting, helps regulate PH and body temperature.

This system includes the heart and blood vessels.  The heart has four chambers.  The right atrium receives deoxygenated blood from the body.  The right ventricle pumps this blood to the lungs.  The left atrium receives oxygen rich blood from the lungs.  The left ventricle pumps the oxygen rich blood out to the body.  With every beat of the heart blood is pumped throughout the body through the blood vessels.  The heart is found behind the rib cage on the left side.  This muscle is encased in dense layers of tissue for protection and support.

There are four different blood types: type A, type B, type AB, and type O.  In order to receive a blood transfusion, the blood must be compatible.  Type O is known as the universal donor and can donate to any other type.  A type AB person can receive blood from any blood type and is known as the universal recipient.
