Be able to write the entire pathway of blood flow through the heart, including vessels entering the heart, chambers, valves, and vessels leaving the heart.

Solution

The heart contains four chambers,two atria and two ventricles.The blood that is returned to the right atrium is deoxygenated and is passed into the right ventricle to be pumped through the pulmonary artery to the lungs for reoxygenation and removal of carbon dioxide.The left atrium receives newly oxygenated blood from the lungs through the pulmonary veins,which is passed into the strong left ventricle to be pumped through the aorta to the different organs of the body.

Right Side of the Heart
Blood enters the heart through two large veins,the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart.As the atrium contracts,blood flows from your right atrium into your right ventricle through the open tricuspid valve.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 pulmonic valve,into the pulmonary artery and to the lungs where it is oxygenated.

Left Side of the Heart
The pulmonary vein empties oxygen-rich blood from the lungs into the left atrium of the heart.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.
