Your Circulatory System The circulatory system consists of the heart, blood, and blood vessels. This system is also sometimes called the cardiovascular system. The heart is the main organ of the circulatory system. The heart beats at different rates depending on whether your body is at rest or at work. There are 3 types of blood vessels: Arteries which carry blood from the heart to the major extremities. Capillaries which deliver oxygen and other nutrients to individual cells. Veins which deliver blood back to the heart.

Your Respiratory System The oxygen that your blood carries comes from the air around you. It is introduced into your body by means of your Respiratory System, which is the body system that exchanges gases between your body and the environment. The principal organ of your respiratory system is your lungs. They exchange oxygen and carbon dioxide.
