Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
As blood flows through the heart it passes valves. Beginning at the right atrium, what is the correct order of valves that blood passes through?
A
Triscuspid, Pulmonary, Mitral, Aortic
B
Aortic, Pulmonary, Tricuspid, Mitral
C
Pulmonary, Aortic, Tricuspid, Mitral
D
Aortic, Mitral, Pulmonary, Tricuspid
Explanation: 

Detailed explanation-1: -Blood that needs oxygen flows from your body into the right atrium. It then flows through the tricuspid valve to the right ventricle. The right ventricle pumps the blood through the pulmonary valve and into your lungs, where it picks up oxygen. The oxygen-rich blood then flows to the left atrium.

Detailed explanation-2: -The blood enters the heart’s right atrium and is pumped to your right ventricle, which in turn pumps the blood to your lungs. The pulmonary artery then carries the oxygen-poor blood from your heart to the lungs. Your lungs add oxygen to your blood.

Detailed explanation-3: -The blood first enters the right atrium. The blood then flows through the tricuspid valve into the right ventricle. When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery. The pulmonary artery carries blood to the lungs where it “picks up” oxygen.

Detailed explanation-4: -The blood enter the right atrium (a) and travels through the tricuspid valve (f) to the the right ventricle (g). The blood then passes through the pulmonary valve (k) to the pulmonary trunk (h) to the lungs (l).

Detailed explanation-5: -Deoxygenated blood starts to run from the body. It flows into Superior/ Inferior Vena Cava. The flow of deoxygenated blood reaches the right atrium. The atrium will push the flow through the Tricuspid valve. The gore stays in the right ventricle. More items •30-Mar-2022
