What Are The Fibrous Strands Connecting The Av Valves To The Myocardium Called
A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more
Made that way : The inner lining of veins forms a continuous covering over the valves and the valve is attached all the way around the inside of the vein--360 degrees. In a real sense, the valves are actually part of the wall. Valves open and close as a passive result of blood going through the valve opening. Their movement responds to blood flow rather than causing it. ...Read more

Chordau tendiniae: The "fibers" are called "chordae" and are similar in function to parachute chords. They prevent the valve leaflets to prolapse (tricuspid and mitral), holding them back just like a parachute chord prevents the parachute from flipping up. If these chords break, the valve will leak. Surgical fixes include annuloplasty (narrowing the valve ring), repairing the chordae, and valve replacement. ...Read moreSee 1 more doctor answer
2 layers: The pericardium is a 'sack' around the heart. Technically the pericardium has 2 layers . The visceral layer that lies against the heart and the parietal layer that is on the out side of the heart. There is a small amt of fluid in between. This protects the heart and acts as a physical barrier.Also acts as a buffer for the heart and insulates it. It can become inflamed and is called pericarditis. ...Read moreSee 1 more doctor answer

Hold valve: Think of valve as a parachute, chordae tendinae are the "ropes" that anchor the valve leaflets or cusps to the heart muscle. Heart muscle contraction pulls on these cords to close the valve, when when heart relaxes then the valve opens. They are an important part of the heart valve apparatus. ...Read moreSee 1 more doctor answer
