What is left Auriculo ventricular aperture?
The left atrioventricular orifice (left atrioventricular opening or mitral orifice) is placed below and to the left of the aortic orifice. It is a little smaller than the corresponding aperture of the opposite side.
What is the name of valve that guards right atrio ventricular aperture?
tricuspid valve
The valves that guard the left and right atrioventricular apertures in man are the tricuspid valve and the bicuspid valve. These valves are present in the heart that prevents the backflow or bidirectional flow of blood.
How many apertures are present in heart?

What is another name for mitral valve?
bicuspid valve
The mitral valve is also known as the bicuspid valve. This is one of the heart’s four valves that help prevent blood from flowing backward as it moves through the heart.
What is the right atrioventricular valve called?
The valves between the atria and ventricles are called atrioventricular valves (also called cuspid valves), while those at the bases of the large vessels leaving the ventricles are called semilunar valves. The right atrioventricular valve is the tricuspid valve.
What are the 4 heart chambers called?
The heart has four chambers: two atria and two ventricles. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle. The right ventricle pumps the oxygen-poor blood to the lungs. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
What are apertures in heart?
The right atrioventricular orifice (right atrioventricular opening) is the large oval aperture of communication between the right atrium and ventricle. Situated at the base of the atrium, it measures about 3.8 to 4 cm.
