Blood flows from right atrium to right ventricle through which valve?
A
semilunar valve
B
tricuspid valve
C
bicuspid valve
D
pulmonary valve
Explanation: 

Detailed explanation-1: -Tricuspid valve: This valve has three leaflets. They allow blood to flow from the right atrium to the right ventricle. They also prevent blood from flowing backward from the right ventricle to the right atrium. Pulmonary valve : This valve also has three leaflets.

Detailed explanation-2: -The tricuspid valves job is to allow blood flowing into the heart from the body to flow to the right ventricle where it’s pumped to the lungs for oxygen. If the tricuspid valve is leaky, blood can flow backwards, causing the heart to pump harder. Over time, the heart becomes enlarged and functions poorly.

Detailed explanation-3: -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-4: -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.

Detailed explanation-5: -Your tricuspid valve opens to let blood travel from your right atrium to your right ventricle. When your right ventricle is full it squeezes, which closes your tricuspid valve and opens your pulmonary valve. Blood flows through your pulmonary artery to your lungs, where it gets oxygen.
