Detailed explanation-1: -Blood flows from the right atrium into the right ventricle through the tricuspid valve. When the ventricle is full, the tricuspid valve shuts to prevent blood flowing backwards into the atrium. Blood leaves the heart through the pulmonic valve into the pulmonary artery and flows to the lungs.
Detailed explanation-2: -Tricuspid valve: Allows blood to pass from the right atrium to the right ventricle; prevents blood from flowing back into the right atrium as the heart pumps (systole).
Detailed explanation-3: -Heart valves control the flow of blood so that it moves in the right direction. The valves prevent blood from flowing backward. The heart has four valves. The tricuspid valve separates the right atrium and right ventricle.
