Where is mitral valve located

Heart Valves, Anatomy and Function. Find a Doctor Find a Doctor. What are heart valves? The four heart valves include the following: tricuspid valve: located between the right atrium and the right ventricle pulmonary valve: located between the right ventricle and the pulmonary artery mitral valve: located between the left atrium and the left ventricle aortic valve: located between the left ventricle and the aorta How do the heart valves function?

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. What is heart valve disease? Heart valves can have one of two malfunctions: regurgitation or leakage of the valve : The valve s does not close completely, causing the blood to flow backward through the valve. This results in leakage of blood back back into the atria from the ventricles in the case of the mitral and tricuspid valves or leakage of blood back into the ventricles in the case of the aortic and pulmonary valves.

Mitral valve prolapse is the most common reason for mitral valve repair in the United States. But in some people, it can cause mitral valve regurgitation, which can cause some symptoms. Mitral valve regurgitation refers to extra blood flowing backward through the mitral valve and into the left atrium. This makes the heart work harder to move blood, causing an enlarged heart.

Mitral valve prolapse can cause mitral valve regurgitation. A variety of other conditions, including a heart attack or rheumatic fever , can also cause it. This results in less blood going through the valve. In response, the heart has to squeeze harder and faster to move enough blood through the heart.

The aortic valve is located between the aorta and the heart's left ventricle. The pulmonary vein delivers oxygenated blood to the heart's left atrium…. The pulmonic valve is one of two valves that allow blood to leave the heart via the arteries.

It is a one-way valve, meaning that blood cannot flow…. The tricuspid valve forms the boundary between the right ventricle and the right atrium. Deoxygenated blood enters the right side of the heart via the…. The vagus nerve is the longest of the 12 cranial nerves. Here, learn about its anatomy, functions, and the kinds of health problems that can occur.

The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes, through which…. The bladder, like the stomach, is an expandable saclike organ that contracts when it is empty. The inner lining of the bladder tucks into the folds…. Combined with the cardiovascular system, the circulatory system helps to fight off disease, helps the body maintain a normal body temperature, and….

The brain is one of your most important organs. Health Conditions Discover Plan Connect. This lets blood flow into the right ventricle that was returned to the right atrium from the body. When the left ventricle contracts, the right ventricle also contracts. This causes the pulmonary valve to open and the tricuspid valve to close. Blood flows out from the right ventricle to the lungs before it is returned to the left atrium as fresh, oxygenated blood.

Regurgitation is a leaky valve. This means the valve doesn't fully close and the blood flows backward through the valve. This results in leakage of blood back into the atria from the ventricles in the case of the mitral and tricuspid valves. Or it leaks back into the ventricles in the case of the aortic and pulmonary valves. This can cause the chambers to be overworked because they have repump the extra blood that was returned. Over time, this can cause structural and functional changes in the heart chambers.

These changes prevent the chambers from pumping blood normally. Stenosis is a narrowed valve. With stenosis, the valve opening is narrowed and the valve doesn't open correctly. This makes it harder for the heart to pump blood across the narrowed valve.

The heart must use more force to pump blood through the stiff stenotic valve or valves. This can also cause structural and functional changes to the different chambers of the heart. These changes prevent the heart from pumping blood normally. This means the valve opening doesn't develop normally during childhood. This prevents blood from passing from an atria to a ventricle, or from a ventricle to the pulmonary artery or aorta.

Blood must find another route.
