left atrioventricular valve
— Navneord
– Engelsk
～ valve with two cusps; situated between the left atrium and the left ventricle
poppet valve
— Navneord
– Engelsk
～ a mushroom-shaped valve that rises perpendicularly from its seat; commonly used in internal-combustion engines
mitral valve
— Navneord
– Engelsk
～ valve with two cusps; situated between the left atrium and the left ventricle
mitral valve prolapse
— Navneord
– Engelsk
～ cardiopathy resulting from the mitral valve not regulating the flow of blood between the left atrium and left ventricle of the heart
mitral valve stenosis
— Navneord
– Engelsk
～ obstruction or narrowing of the mitral valve (as by scarring from rheumatic fever)
semilunar valve
— Navneord
– Engelsk
～ a heart valve with cusps shaped like half-moons; prevents blood from flowing back into the heart
right atrioventricular valve
— Navneord
– Engelsk
～ valve with three cusps; situated between the right atrium and the right ventricle; allows blood to pass from atrium to ventricle and closes to prevent backflow when the ventricle contracts
safety valve
— Navneord
– Engelsk
～ a valve in a container in which pressure can build up (as a steam boiler); it opens automatically when the pressure reaches a dangerous level
