Differentiate between Tricuspid and bicuspid valve

The first _______ sound is produced by the closure of tricuspid and bicuspid valves .

The tricuspid and bicuspid valves open at the same time .

Differentiate between bicuspid and tricuspid valve.

Which of the following statement is CORRECT ? I. Heart, the mesodermally derived organ, is situated in the thoracic cavity, in between the two lungs , slightly tilted to the left. II. During joint diastole , tricuspid and bicuspid valves are open and the semilunar values are closed. III. The first heart sound (lub) is associated with the closure of the tricuspid and biscuspid valves whereas the second heart sound (dub) is associated with the closure of the semilunar valves . IV. Neural signals through the sympathetic nerves can increases the rate of hearbeat, the strength of ventricular contraction and thereby the cardiac output.
