The is one of four
Chambers (two
Atria and two
Ventricle s) in the
Human Heart . It receives de-
Oxygen ated
Blood from the
Right Atrium via the
Tricuspid Valve , and pumps it into the
Pulmonary Artery via the
Pulmonary Valve .
It is triangular in form, and extends from the right atrium to near the
Apex Of The Heart .
Its anterosuperior surface is rounded and convex, and forms the larger part of the sternocostal surface of the heart.
Its under surface is flattened, rests upon the
Diaphragm , and forms a small part of the diaphragmatic surface of the heart.
Its posterior wall is formed by the
Ventricular Septum , which bulges into the right ventricle, so that a transverse section of the cavity presents a semilunar outline.
Its upper and left angle forms a conical pouch, the
Conus Arteriosus , from which the
Pulmonary Artery arises.
A tendinous band, which may be named the tendon of the conus arteriosus, extends upward from the right atrioventricular fibrous ring and connects the posterior surface of the conus arteriosus to the aorta.
The wall of the right ventricle is thinner than that of the left, the proportion between them being as 1 to 3; it is thickest at the base, and gradually becomes thinner toward the apex.
The cavity equals in size that of the left ventricle, and is capable of containing about 85 c.c.
Its interior presents the following parts for examination:
