There are 4 heart chambers. The two upper chambers are called atria while the two lower chambers are called ventricles. The valve separating the atria from the ventricles is called the atrioventricular valve. Then you would have your right and left atrioventricular valves.
The valve between the right atrium and right ventricle is the tricuspid valve.
The AV valves (or atrial ventricular valves) separate the upper from the lower chambers.
Valves made of tendons
Interatrial septum
They are the two lower chambers if the heart, responsible for pumping blood out to the body.
The upper heart valves are called atriums, and the lower heart valves are called ventricles.
Mitral valve stenosis refers to a condition in the heart in which one of the valve openings has become narrow and restricts the flow of blood from the upper left chamber (left atrium) to the lower left chamber (left ventricle).
The heart is divided into 4 chambers: 2 on the right hand side and 2 on the left. Each upper chamber is known as an atrium and each lower chamber as a ventricle. The 4 compartments are known as: the right atrium; the right ventricle; the left atrium and the left ventricle.
The question is not clear. You may have mitral valve prolapse, mitral stenosis or mitral regurgitation. Mitral valve prolapse is a heart problem in which the valve that separates the upper and lower chambers of the left side of the heart does not close properly. Mitral stenosis is a heart valve disorder that involves the mitral valve. This valve separates the upper and lower chambers on the left side of the heart. Stenosis refers to a condition in which the valve does not open fully, restricting blood flow. Acute mitral regurgitation is a disorder in which the heart's mitral valve suddenly does not close properly, causing blood to flow backward (leak) into the upper heart chamber when the left lower heart chamber contracts. In open surgery, the surgeon makes a large incision (cut) in your breastbone to reach the heart. http://www.nlm.nih.gov/medlineplus/ency/article/000180.htm http://en.wikipedia.org/wiki/Mitral_prolapse http://www.nlm.nih.gov/medlineplus/ency/article/000175.htm http://en.wikipedia.org/wiki/Mitral_stenosis http://www.nlm.nih.gov/medlineplus/ency/article/000177.htm http://www.nlm.nih.gov/medlineplus/ency/article/000176.htm http://en.wikipedia.org/wiki/Mitral_regurgitation http://www.nlm.nih.gov/medlineplus/ency/article/007411.htm http://www.nlm.nih.gov/medlineplus/ency/article/007412.htm
The AV valves separate the upper and lower chambers of the heart. The bicuspid valve is on the left, and the tricuspid on the right.
The heart has upper and lower chambers.
The lower chamber is the ventricle, and there are 2 upper chambers (they are known as atria).
"The right side of the heart is completely separate from the left side by a wall of tissue called septum. Each side has two compartments, or chambers and upper chamber and lower chamber." ~Human Biology and Health; Science Explorer; Chapter 3, Sec. 1
The right atrium (upper chamber) and the right ventricle (lower chamber)
They are the two lower chambers if the heart, responsible for pumping blood out to the body.
The Mitral Valve is located between the Left Atrium ( Left upper chamber) and the Left Ventricle (Left lower chamber)
The Mitral Valve is located between the Left Atrium ( Left upper chamber) and the Left Ventricle (Left lower chamber)
upper chamber and the lower chamber upper chamber consist the atrium while the lower chamber consist the ventricles
The Mitral Valve is located between the Left Atrium ( Left upper chamber) and the Left Ventricle (Left lower chamber)
It is important because if the blood stayed in the upper chamber forever there can become a major problem with your body
Upper chambers of heart are the left and right atrium Lower are the left and right ventrical atrioventricular valves separate the two. Bicuspid (mitrial) valve separates the left atrium/ventrical and the tricuspid separates the right atrium/ventrical.
