Circulatory system
On average, your body has about 5 liters of blood continually traveling through it by way of the circulatory system. The heart, the lungs, and the blood vessels work together to form the circle part of the circulatory system. The pumping of the heart forces the blood on its journey.
The heart has a left and right side that work together to pump and receive blood. the rate at which our heart pump depend on our activities.
How does it work ?
Well,the heart has 4 chambers right atrium, right ventricle, left atrium and left ventricle. Oxygen and blood come from the head and body to the right side of our heart in to the right atrium then in to the right ventricle to be pump to the lungs . The left atrium and the left ventricle gets the oxygen rich blood and pump it back in to the body and head and that is the circulatory system.
