Question

The opening between the right atrium and the right ventricle is guarded by the valve named:
A. Bicuspid valve
B. Tricuspid valve
C. Mitral valve
D. Semilunar valve

Answer 1

Hint: In this valve the blood passes from the right atrium and the right ventricle. Also, it is processed when the right atrium contracts then the muscular force will push the blood through the pulmonary artery into the pulmonary semilunar valve.

Complete answer:
The opening between the right atrium and the right ventricle is guarded by the valve called the tricuspid valve. In this the blood passes from the right atrium and the right ventricle through this valve. When the right ventricle contracts with the muscular force it pushes the blood through the pulmonary semilunar valve into the pulmonary valve.
This Tricuspid valve is one of the two main valves on the right side of your heart, basically this valve has three flaps that are open and close, In this process it allows the blood to flow from the right atrium to the right ventricle. It is preventing blood from flowing backward.
This valve has a main function that separates the top right chamber of the heart from the bottom right chamber of the heart. It opens to allow the blood that is to flow from the right atrium to the right ventricle. It also prevents the blood flow from the right ventricle to the right atrium. This valve has another name such as the right atrioventricular valve.
option A: Bicuspid valve, this is the wrong answer because the bicuspid valve is based on the left atrium and left ventricle. So it is the wrong answer.
For option B: Tricuspid valve, this is a right answer, because of this valve blood passes right atrium to the right ventricle so it is the right answer.
For option C: Mitral valve, this is wrong answer because mitral valve is the other name of bicuspid valve
So it is wrong
For option D: Semilunar valve is the wrong answer because it determines the passage of blood between the ventricles and the main arteries.
So, the correct answer is “Option B”.

Note:
This tricuspid valve usually contains three leaflets, they are anterior, posterior and finally a septal leaflet. This regression is known as tricuspid regurgitation and it is common in heart disease and often leads to drug abuse. The tricuspid valve has another name that is the right atrioventricular valve.
