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

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.

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 .

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.

∙ 11y agomy guess is the pulmonary circulation because that is its gateway

What will happen if one of the system fails to carry out of its function properly?
If one part of a system fails to carry out its function properly the rest of the system will be affected and other parts of the system will work harder.
What will happen if one part of the system fails to carry out function properly?
If one part of a system fails to carry out its function properly the rest of the system will be affected and other parts of the system will work harder.
What will happen if one part of the system fails carry out its function properly?
If one part of a system fails to carry out its function properly the rest of the system will be affected and other parts of the system will work harder.

Which body systems will be directly affected if a tendon gets torn and cannot function properly?
the muscular system and the skeletal system
What might happen if your cardiovascular did not function properly?
If the cardiovascular system doesn't work, then obviously organs would be affected. The first organ affected will be the lungs.

How does the excretory system help the circulation system to function properly?
They send signals to the blood vessels to dilate they also keep the heart from pumping too fast or pumping too slow.
Do you think that an organism's nervous system is affected by what it eats?
definitely. For one thing, you nervous system can only utilize carbohydrates, so if you don't get enough it does not function properly.
If the circulation system is a closed system how is it affected by laying down?
Not much effect at all. Like a straw filled with water without any air bubbles and closed at both ends, you can rotate the straw any which way and the water will not move inside. The only effect the circulation will have is the easing of the circulation through the bloodstream as the heart slows slightly during rest.
