mitral valve
mitral valven. A valve of the heart, composed of two triangular flaps, that is located between the left atrium and left ventricle and regulates blood flow between these chambers. Also called bicuspid valve.mitral valve n (Anatomy) the valve between the left atrium and the left ventricle of the heart, consisting of two membranous flaps, that prevents regurgitation of blood into the atrium. Also called: bicuspid valve mi′tral valve`
n. the valve between the left atrium and left ventricle of the heart, consisting of two triangular flaps of tissue, that prevents blood from flowing back into the atrium when the ventricle contracts. Also called bicuspid valve. Compare tricuspid valve.

The Heimlich valve is less than 13 cm (5 inches) long and facilitates patient ambulation; it can be used in many patients instead of a traditional water seal drainage system.ileocecal valve (ileocolic valve) the valve guarding the opening between the ileum and cecum.mitral valve the valve" >cardiac valve between the left atrium and left ventricle, usually having two cusps (anterior and posterior). Called also bicuspid valve. Valves of the heart. The right heart pumps the venous blood into the lungs. The oxygenated blood returns from the lungs into the left atrium and is propelled by the left ventricle into the aorta. The insets show closed valves: the tricuspid valve has three leaflets, whereas the mitral valve has two leaflets. The aortic and pulmonary artery valves have three leaflets and resemble one another except for the fact that the coronary arteries originate from behind the cusps in the aorta.
