Answer #1

Answer : Rapid filling

Atrial contraction .
isovolumetric relaxation.

Explanation : During ventricular diastole the ventricles are passively filling and atria are contracting.

Isovolumetric relaxation is the early ventricular diastole - During the brief period of time following the repolarization of the ventricles , the ventricles relax. Because the blood remaining in the ventricles is no longer compressed, ventricular pressure drops rapidly. Once ventricular pressure falls below the pressure in the aorta and pulmonary trunk, blood flows back towards the ventricles from these arteries causing the semilunar valves to close. Closure of the aortic semilunar valve causes a brief rise in aortic pressure as backflowing blood rebounds off the closed aortic semilunar valve cusps...Thanks dear student

    2. Aortic valve stenosis is a hardening of the aortic valve which makes it difficult to eject blood from the left ventricle. What effect does this have on the normal electrical and/or pressure events of the cardiac cycle? In your answer, you should include terms and processes such as right atrium, tricuspid valve,right ventricle, pulmonary valve, pulmonary circulation, left atrium, bicuspid valve, left ventricle, aortic valve, systemic circulation, systole, diastole, ventricular systole/diastole, atrial systole/diastole, passive ventricular filling, “atrial kick,” isovolumic...

    Question 19 (1 point) Ventricular filling slows in the second half of this period, as indicated by a plateau in the ventricular volume trace. Why do you think that passive filling of the ventricles slows? The pressure gradient for blood to flow from the atria into the ventricles becomes less. Ventricular pressure is now greater than atrial pressure, so there is a tendency for blood to flow back into the atria. The ventricles have reached maximum blood capacity, and cannot...

    1. True -False. If a statement is True, place a T to the left of it. If a statement is False, place an F to the left of it. Thin filaments in smooth muscles attach to Z discs. The majority of ventricular filling occurs during the period of atrial contraction known as the period of rapid filling. Closure of the atrioventricular valves occurs at the end of diastole/beginning of systole. Tetanus in skeletal muscles is the result of increasing the...
