First valve in blood flow of heart
A
aortic
B
mitral
C
pulmonary
D
tricuspid
Explanation: 

Detailed explanation-1: -The tricuspid valve sits between the heart’s two right chambers. The tricuspid valve consists of three thin flaps of tissue (called cusps, or leaflets). These valve flaps open to let blood flow from the upper right chamber (right atrium) to the lower right chamber (right ventricle).

Detailed explanation-2: -Blood first enters the heart’s right atrium. A muscle contraction forces the blood through the tricuspid valve into the right ventricle. When the right ventricle contracts, blood is forced through the pulmonary semilunar valve into the pulmonary artery. Then it travels to the lungs.

Detailed explanation-3: -Two of the valves, the mitral and the tricuspid valves, move blood from the upper chambers of the heart (the atria) to the lower chambers of the heart (the ventricles). The other two valves, the aortic and pulmonary valves, move blood to the lungs and the rest of the body through the ventricles.

Detailed explanation-4: -The tricuspid valve controls the flow of blood from your heart’s right atrium (top chamber) to the right ventricle (bottom chamber). Blood can leak backward into the atrium from the leaky tricuspid valve, causing your heart to pump harder to move blood through the valve.
