The tricuspid valve occurs between
A
Right auricle and right ventricle
B
Right auricle and left ventricle
C
Left auricle and left ventricle
D
Left ventricle and right ventricle
Answer
Right auricle and right ventricle
Explanation
Solution
The two atria are separated from the ventricles by membranous valves. The valve separating the right auricle from the right ventricle is known as the right atrioventricular valve or tricuspid valve (as it is made of three flaps or cusps). The valve separating the left atrium and the left ventricle is called left atrioventricular valve or the bicuspid valve or the mitral valve (since it is made of two flaps).
