MICROANATOMY

Detailed explanation-1: -The pulmonary artery carries oxygen-poor blood from the right ventricle into the lungs, where oxygen enters the bloodstream. The pulmonary veins bring oxygen-rich blood to the left atrium. The aorta carries oxygen-rich blood to the body from the left ventricle.

Detailed explanation-2: -Once deoxygenated blood is pumped from the right atrium through the tricuspid valve into the right ventricle, contraction of the right ventricle will push blood through the pulmonic valve into the pulmonary artery that will carry deoxygenated blood to the lungs.

Detailed explanation-3: -Aortic valve connects your left ventricle and aorta (large artery that carries blood throughout your body). Mitral valve connects your left atrium and left ventricle. Pulmonary valve connects your right ventricle and pulmonary arteries (arteries that carry blood to your lungs).
