Question

What is the pressure of the blood in ventricles with which it flows when the valves ?​

Answer 1

Answer:

As blood flows into the atria, the pressure will rise, so the blood will initially move passively from the atria into the ventricles. When the action potential triggers the muscles in the atria to contract (atrial systole), the pressure within the atria rises further, pumping blood into the ventricles.

Explanation:

The normal right ventricular systolic pressure is less than 30 mm Hg and the end-diastolic pressure is about 5 mm Hg.

Answer 2

Answer:

The end-diastolic pressure is about 5 mm Hg

Explanation:

When the heart pushes blood around the body during systole, the pressure placed on the vessels increases. This is called systolic pressure. When the heart relaxes between beats and refills with blood, the blood pressure drops. This is called diastolic pressure.
