) As the muscles in the walls of atrium contract blood flows through the tricuspid valve into the right ventricle. The tricuspid valve (AV atrioventricular valve) has three flap like cusps. Its role is ensure blood flows in a one way direction from the right atrium into the right ventricle. (Clevelandclinicorg, 2015)
The process of the blood filling the ventricle is called ventricular diastole.(Wikipediaorg, 2015)
When the ventricle is full the tricuspid valve shuts. The tricuspid valve has fibrous strands which are called cordae tendinae. These strands attach to papillary muscles that contract when the ventricles contract. This “generates tension” (Biologyguidenet, 2015) on the tricuspid valve and prevents blood from bulging and flowing back
