Question

The tricuspid valve occurs between the

• A. Right auricle and right ventricle
• B. Pulmonary aorta
• C. Carotico-systemic aorta and left ventricle
• D. Left ventricle

Answer 1

The correct option is A Right auricle and right ventricle

The tricuspid valve lies between the right atrium and the right ventricle. The function of the valve is to prevent backflow of blood into the right atrium. The normal tricuspid valve usually has three leaflets and three papillary muscles. They are connected to the papillary muscles by the chordae tendineae, which lie in the right ventricle. Tricuspid valves will not always consist of three leaflets and may also occur with two or four leaflets and the number may change during one's lifetime.

So, the correct answer is option A.
