Question

Tricuspid valve is found in between

(a) sinus venosus and right auricle

(b) right auricle and right ventricle

(c) left ventricle and left auricle

(d) ventricle and aorta

Answer 1

Correct Option (b) right auricle and right ventricle

Explanation:

Right auricle opens in right ventricle through a wide circular right auriculoventricular aperture guarded by right auriculoventricular valve which is formed of three flaps called cusps, so it is called tricuspid valve. It regulates the unidirectional flow of blood from right auricle to right ventricle.
