Semilunar valves open during ventricular diastole.

Text Solution

AI Generated Solution

To solve the question regarding whether semilunar valves open during ventricular diastole, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding Ventricular Diastole**: - Ventricular diastole is the phase of the cardiac cycle when the ventricles of the heart relax. During this phase, the heart fills with blood. 2. **Role of Atrioventricular Valves**: ...

Read the following statements and select the correct option. A. Damage to chordae tendinae of semilunar valves in aorta causes back flow of blood in left ventricle. B. Closure of atrio-ventricular valves during ventricular systole generates first heart sound.

Read the given statements and select the correct option w.r.t. true and false : br (a) Duration of each cardiac cycle is 0.8 seconds which can be altered in fear or fight conditions, br (b) Rapid passive ventricular filling takes place when auricles are in diastole and auriculoventricular valves remain closed, br (c) Semilunar valves open when intraventricular pressure exceeds the pressure within aorta, br (d) Sinoatrial node comprises of autoexcitable tissue.

During diastole

Rise in ventricular pressure during ventricular systole leads to closure of atrioventricular valves which generates 1) Lub sound 2) Dub sound 3) Third heart sound 4) Heart murmurs

Assertion : The pause between the end of the second sound and the beginning of the first sound coincides with ventricular diastole. Reason : The second sound (dupp) is created by the closure of the semilunar valve.
