Tricuspid valve is present between
A
left atrium and left ventricle
B
right and left atria
C
right and left ventricles
D
right atrium and right ventricle
Answer
right atrium and right ventricle
Explanation
Solution
Tricuspid valve (right atrioventricular valve) is a valve, consisting of three flaps, situated between the right atrium and the right ventricle of the mammalian heart. When the right ventricle contracts, forcing blood into the pulmonary artery, the tricuspid valve closes the aperture to the atrium, thereby preventing any backflow of blood. The valve reopens to allow blood to flow from the atrium into the ventricle.
