The Circulatory System – Big Write

The human heart is a vital organ in the body which pumps blood. It carries blood and oxygen to other parts of the body. It beats around 100,000 times a day and translates about 2,000 gallons of blood everyday. It sits in the chest just a little bit to the left, in front of the left lung. Your heart is about the size of a clenched fist. It also pumps blood every time it beats. If you didn’t have a heart then you would die.

First, the blood cell goes through the right atrium. Then, it goes through the tricuspid valve and the right ventricle. The blood vessel goes through the arteries deoxygenated, then the heart sends the oxygenated blood through the veins. After that, it comes into the left atrium, left ventricle,  aortic valve and to where the oxygen is needed. Then, the cycle restarts.

Here are some facts: Did you know that every second, 8 million blood cells die, and the same number are born? The heart beats around 3 billion times in a persons life.
