flow of blood from body tissue to the heart and back
systole
contraction phase of the heartbeat
tricuspid valve
located between the right atrium and right ventricle; has 3 leaflets or cusps
valve
structure in veins or in the heart that temporarily closes an opening so blood flows in only one direction
vein
thin-walled vessel that carries blood from body tissues and lungs back to heart; contains valves to prevent back flow of blood

obstruction of blood flow to organ
unstable angina
chest discomfort or pain caused by an insufficient flow of blood and oxygen to the heart

infection along the edges of the heart valves
Mitral valve prolapse (MVP)
heart valve disease in which the flaps (also called leaflets or cusps) of the mitral valve become enlarged or stretched.
Murmur
a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the heart valves or near the heart.
