The flow of blood through the heart is controlled by four�valves: thetricuspid,�pulmonary semilunar,�mitral, and�aortic semilunar valves. The�tricuspid valve�controls the opening between the right atrium and the right ventricle. The�pulmonary semilunar valve�is located between the...
(AV) valves, located between the atrium and the ventricle on either side of the heart: The tricuspid valve on the right has three cusps, the mitral valve on the left has two. The other two valves regulate blood flow out of the heart. The aortic valve manages blood flow from the left ...
There is only one place in the human body with three duplicate heart valves, called the tricuspid valve. The valves of the heart are structures which ensure blood flows in only one direction. They are composed of connective tissue and endocardium (the inner layer of the heart). There are f...

Oxygen rich blood, red blood, then enters the left side of the heart, composed of the left atrium and ventricle and is pumped through the aorta to the body to supply tissues with oxygen. Four valves within the heart keep your blood moving the right way. The tricuspid, mitral, pulmonary,...
The heart valves work the same way as one-way valves in the plumbing of your home. They prevent blood from flowing in the wrong direction. Each valve has a set of flaps, called leaflets or cusps. The mitral valve has two leaflets; the others have three. The leaflets are attached to an...
The heart valves open and close due to A. stimulation by the sympathetic(交感) and parasympathetic(副交感) nerves B. a pressure difference on the two sides of the valve C. Na+ and K+ fluxes during ventricular depolarization D. turbulent flow in the atria and ventricles E. None of the ...
The heart can be safely opened and its valves repaired. Clogged blood vessels can be cleaned out, and broken ones mended or replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, ...
