What circulation system is affected if the mitral valve does not close properly?

Answer 1

The mitral valve is also known as the left atrioventricular valve. It prevents blood flow back into the atria while the ventricles are contracting. There are also two types of circulation through the heart. The systemic circuit carries blood to and from all the body tissues and is operated by the left side of the heart. The pulmonary circuit carries blood to and from the lungs and is operated by the right side of the heart. Because this valve is located on the left side, the systemic circulation is affected when the mitral valv is not functioning correctly.

Answer 2

Well, this is when the flaps of the valve are "floppy" and don't close tightly. These flaps normally help seal or open the valve. The mitral valve controls blood flow between the upper and lower chambers of the left side of the heart. The mitral valve allows blood to flow from the left atrium into the left ventricle, but not back the other way. So bascially, backflow of blood in your heart .

Answer 3

To put it simply: it will affect the systemic circulation.

Our body consists of 2 circulations. The pulmonary circulation goes around the lungs (out of the right ventricle - lungs - back into the left atrium). The systemic circulation goes around the rest of the body (out of the left ventricle - body - then back into the right atrium).

The mitral valve is between the left atrium and left ventricle. It's job is to prevent blood going back into the left atrium when the left ventricle contracts. If it's working properly, when the left atrium contracts, the mitral valve will open and blood will flow into the left ventricle. Then, when the left ventricle contracts, the mitral valve will shut, forcing blood to flow out through the aorta (through the aortic valve).

If the mitral valve prolapses, this process will become less efficient or even stop working. The left ventricle will contract, but blood won't flow through the aorta. As a result blood won't go around the body. In other words, the systemic circulation will be impaired.

Answer 4

All blood flow circulation is affected due to the fact the heart pumps blood through the entir body.

Answer 5

my guess is the pulmonary circulation because that is its gateway

Answer 6

The systemic circulation is affected.
