Path of Blood Through the Heart and Pulmonary Circuit

Step 3

Blood flow from right ventricle through the open pulmonary valve and into the pulmonary trunk

Step 6

Blood flows from the left atrium and through the mitral valve (or biscupid valve) and into the left ventricle

Step 7

Blood flows through open aortic valve and into the aorta, joining the systemic circuit, carrying oxygenated blood to all capillaries through the body

Step 2

Blood flows through open tricuspid valve and into right ventricle

Step 4

Blood pumps into right and left pulmonary arteries into the capillary beds in the left and right lungs; gets oxygenated and gives up carbon dioxide

Step 1

Deoxygenated blood from systemic circuit enters from inferior and superior vena cavae into right atrium

Step 5

Oxygenated blood flows into right and left pulmonary veins and into the left atrium
