Question

Write the function of valves present in between arteries and ventricles

Answer 1

As the heart muscle contracts and relaxes, the valves open and shut, letting blood flow into the ventricles and atria at alternate times. The following is a step-by-step illustration of how the valves function normally in the left ventricle:

After the left ventricle contracts, the aortic valve closes and the mitral valve opens, to allow blood to flow from the left atrium into the left ventricle.
As the left atrium contracts, more blood flows into the left ventricle.
When the left ventricle contracts again, the mitral valve closes and the aortic valve opens, so blood flows into the aorta.

Answer 2

Hello!!

Let's unlock your question!!

The function of the valves present between the arteries and ventricles is to prevent back flow of the blood.
