circulatory system

how it works

The circulatory system is a crucial body system that impacts every cell in our bodies. The heart is the muscular organ which pumps blood through the arteries and veins. It gives the cells nutrients and oxygen, while it takes away waste. It transports oxygenated blood from the heart and delivers oxygen and nutrients to the body's cells. It then returns the deoxygenated blood to the heart. An average adult has 5-6 quarts of blood. The system of blood vessels in the human body can measure to about 60 miles!

The circulatory system maintains homeostasis by delivering oxygen and nutrients continuously to each cell in the blood. It also helps with removal of waste. This helps to maintain the correct balance.


Heart disease, also called cardiovascular disease, is the leading cause of death for adults in America.


The circulatory system is highly interactive with other body systems.
