Step 1

Blood enters the heart through two large veins, the Inferior and the superior vena cava

Step 2

The right atrium receives deoxygenated blood from the vena cava and pumps it into the right ventricle, which then sends it to the lungs to be oxygenated

Step 3

Blood flows from your right atrium to your right ventricle, through the open tricuspid valve

Further Explanation

When the ventricles are full, the tricuspid valves shut, which prevents back flow

Step 4

Blood then flows through the pulmonic valve, where it then leaves the heart through the pulmonary artery and into the lungs

Step 5

The pulmonary vein empties oxygen-rich blood, into the left atrium

Step 6

Blood flows from the left atrium to the left venticle through the open mitral valve

Further Explanation

When the ventricles are full, the mitral valve shuts, which prevents back flow

Step 7

Blood leaves the heart through the aortic valve into the aorta and to the body

Further Explanation

This pattern is repeated causing blood to flow continuously to the heart, lungs, and body
