BLOOD FLOW

The right and left sides of the heart work together.
The pattern described below is repeated over and over, causing blood to flow continuously to the heart, lungs, and body.

Right Side
1) Blood enters the heart through two larg veins, the inferior and superior vena cava, emptying oxygen-- poor blood from the body into the right atrium.
2) As the artium contracts, blood flows from your right ventricle through the open tricuspid valb.
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the atria while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonary atrery and to the lungs where it is oxygenated.

Left Side
The pulmonary vein empties oxygen-- rich blood from the lunghs into the left atrium.
As the atrium contracts, blood flows from your left atrium into your left ventricle through the open mitral valve.
When the ventricle is full, the mitral valve shuts. This prevents blood from flowing backward into the atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the aortic valve, into the aorta and to the body.

How Does Blood Flow Through Your Lungs?

Once blood travels through the pulmonic valve, it enters your lungs. This is called the pulmonary circulation. From your pulmonic vavle, bloodtravels to the pulmonary artery to tiny capillary vessels in the lungs.

Here, oxygen travels from the tiny air sacs in the lungs, through the walls of the capillaries, into the blood. At the same time , carbon dioxide, a waste product of metabolism, passes from the blood into the air sacs. Carbon dioxide leaves the body when you exhale. Once the blood is purified and oxygenated, it travels back to the left atrium through the pulmonary veins.
