The heart has four chambers. Deoxygenated blood enters the right atrium from around the body via the superior and inferior vena cavae, and travels down through the tricuspid valve into the right ventricle.
The right ventricle pumps the deoxygenated blood to the lungs to be oxygenated, via the pulmonary artery (the only artery that carries deoxygenated blood). It returns via the pulmonary vein (the only vein that carries oxygenated blood) into the left atrium.
Oxygenated blood then enters the left ventricle (the heart's principle pumping chamber, and has particularly thick muscular walls) from the left atrium through the mitral valve. The left ventricle pumps the oxygenated blood at sufficient pressure to travel round the entire body, through the aortic valve and into the aorta.

∙ 14y agoThere are 4 valves in the heart. The tricuspid valve and the mitral valve separate the atria from the ventricles and close during systole. The pulmonic and aortic valves prevent backflow from the pulmonary circulation and the systemic circulation respectively and close during diastole.

∙ 9y agoMitral valve lies between left atrium and left ventricle. It is bicuspid valve. means there are two cusps in this valve. You have tricuspid valve between right atrium and right ventricle. There are three cusps in this valve. Blood can flow from atrium to ventricle. Reverse flow is prevented by the valve mechanism. You papillary muscles attached to valves by way of fine tendons called as chordae tendineae. These beautiful papillary muscles contract during contraction of the ventricles to hold the cusps of the valves and prevent the prolapse of the valves.

What is the medical term meaning reverse flow of blood through the mitral or tricuspid valves?
Mitral regurgitation or tricuspid regurgitation is the medical term meaning backflow of blood through the mitral or tricuspid valves, respectively.
Valves separating atria and ventricles are cal led what valves?
for the right atrium and right ventricle, the tricuspid valve separates the two. For the left, the mitral valve separates the two.
What are the names for the two different sets of heart valves?
Atrioventricular valves Bicuspid Valve Tricuspid valve Pulmonary valve Aortic valve these are all the valves which are part of the heart.

Valves of the heart: Bicuspid, Tricuspid, Mitral, Aortic
What are the names of the valves in the top part of the ventricles?
tricuspid valve and mitral valve
The second heart sound is caused by?
Closure of the two atrioventricular valves, specifically the tricuspid and mitral valves.
