Right Atrioventricular Valve (Noun)
Meaning
Valve with three cusps; situated between the right atrium and the right ventricle; allows blood to pass from atrium to ventricle and closes to prevent backflow when the ventricle contracts.
Classification
Nouns denoting body parts.
Examples
- The right atrioventricular valve is formed from three cusps and is crucial for maintaining a unidirectional flow of blood from the right atrium to the right ventricle.
- A deformation in the shape of one of the right atrioventricular valve cusps often hinders its function of letting blood pass into the ventricle.
- Blood in the atrium flows freely towards the ventricle when the right atrioventricular valve is wide open during diastole.
- At the onset of systole, the contraction of the ventricle induces closure of the right atrioventricular valve.
- The right atrioventricular valve in humans typically comprises the anterior, posterior, and septal cusps, working together in a harmonious manner to ensure the one-way flow of blood.
