From deoxygenated blood entering the heart to oxygenated blood leaving the heart, in which order will the blood pass through the following valves?
Pulmonary valve
Aortic valve
Tricuspid valve
Bicuspid valve
The Correct Answer is C, A, D, B
- Deoxygenated blood from the body enters the right atrium, passes through the tricuspid valve into the right ventricle.
- From the right ventricle, blood moves through the pulmonary valve into the pulmonary arteries and goes to the lungs for oxygenation.
- Oxygenated blood returns to the left atrium and passes through the bicuspid (mitral) valve into the left ventricle.
- Finally, the left ventricle pumps oxygenated blood through the aortic valve into the aorta for distribution to the body.
