What is the Hearts pumping action order?

Answer 1

It starts out in the right atrium to the tricuspid valve into the right ventricle then the pulmonic valve to the pulmonary arteries. Then it goes to the capillaries to the pulmonary veins then the left atrium to mitral valve then left ventricle which then goes to the aortic valve to the aorta. The oxygenated blood goes through the body then diffusion happens of the hormones, nutrients, and oxygen into the body cells. Then oxygen-poor blood goes to the superior and inferior vena cava and back to the right atrium.

This happens over and over again because the circulatory system is a closed system.
