right atrioventricular orifice
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 4 cm. in diameter and is surrounded by a fibrous ring, covered by the lining membrane of the heart; it is considerably larger than the corresponding aperture on the left side, being sufficient to admit the ends of four fingers.
It is guarded by the tricuspid valve.
