Are there any structures within the heart or vessels that prevent the backflow of blood? If so, what are they and where are they

Answer:

Are there any structures within the heart or vessels that prevent the backflow of blood? If so, what are they and where are they located?

Explanation:

<em>The heart is made up of four cavities. These are the following</em>: Two ventricles and Two atria.

<em>The left ventricle is the one that exerts the greatest muscular strength, because from here the blood is pumped to the systemic circulation. To prevent blood from flowing backward between two beats, there are several types of heart valves</em>: one type between the atria and the ventricles, and another between the ventricles and arteries.

The semilunar valves in turn prevent blood from returning from the pulmonary artery and the aorta to the ventricles, when after pumping they dilate again for muscle relaxation.

<u><em>The answer is</em></u>: <u>Yes, and they are semilunar valves.</u>
