PATHOLOGY

Detailed explanation-1: -Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle. The mitral valve separates the left atrium and left ventricle.

Detailed explanation-2: -tricuspid valve: located between the right atrium and the right ventricle. pulmonary valve: located between the right ventricle and the pulmonary artery. mitral valve: located between the left atrium and the left ventricle. aortic valve: located between the left ventricle and the aorta.

Detailed explanation-3: -The chambers at the top are called atria and these chambers receive the blood from the veins supplying the heart. Blood flows from the atria to the ventricles, which are separated from the atria by atrioventricular valves to prevent blood flowing in the opposite direction.
