AV Valves

Atrioventricular valves are valves in the heart that lie between the atria and the ventricles to prevent the backflow of blood during ventricular contraction.

Papillary Muscles

Muscular projections from the ventricular walls of the heart that attach to the cusps of the atrioventricular valves via the chordae tendineae and prevent valve inversion.

Regurgitation

The backward flow of blood through a valve in the heart due to the valve not closing properly, or the process of vomiting undigested food.

Cardiac Muscle Tissue

Tissue composed of cells that form the myocardium of the heart, responsible for the rhythmic contractions that pump blood.
