--The circulatory system is also known as the cardiovascular system.
-- It is composed of the heart, blood, blood vessels and also includes the lungs.
The primary function of the circulatory system to distribute oxygen, nutrients, hormones and other gases to cells of the other body systems. It delivers all the necessary components needed for all the cell activities. Without the circulatory system, we would not be alive.
It is our blood that carries these necessary nutrients, hormones, and oxygen. All these components trigger certain processes that keep other organs functioning. It also plays a role in eliminating waste by carrying them to the necessary organs that will filter them out. Without a way to dispose of waste, the body will eventually die.
