PATHOLOGY

Detailed explanation-1: -The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA). From there, the blood flows through the right and left pulmonary arteries into the lungs.

Detailed explanation-2: -The right AV valve is called the tricuspid valve, the left is called the mitral valve. The pulmonary valve permits blood to flow from the right ventricles into the pulmonary artery, and the aortic valve permits blood to flow from the left ventricle into the aorta.

Detailed explanation-3: -The pulmonary artery and aorta are the main arteries that carry blood to the lungs and the rest of the body. The flow of blood through the blood vessels and chambers of the heart is controlled by valves. The four main valves are: 1. Tricuspid valve: This separates the right atrium and right ventricle.
