Cavity of ventricle: anatomy, location and function

The cavity of the ventricle is the blood-filled chamber of the right or left ventricle. The ventricles are the main pumping chambers; the right drives blood to the lungs, the left to the body.

Cavity of ventricle at a glance

What it is
The cavity of the ventricle is the blood-filled chamber of the right or left ventricle.
Location
The right ventricle receives blood through the tricuspid valve and ejects it through the pulmonary valve. The left ventricle receives blood through the mitral valve and ejects it through the aortic valve. Both walls bear trabeculae carneae and papillary muscles.
Function
The ventricles are the main pumping chambers; the right drives blood to the lungs, the left to the body.
Body system
Cardiovascular · paired (left and right)

Key facts

  • The left ventricular wall is about three times thicker than the right.
  • The right ventricle is crescent-shaped in cross-section and has a smooth outflow part (conus arteriosus); the left is conical and almost circular in section.
  • The two ventricles eject the same volume with each beat, about 70 mL at rest.
