Ventricle
The right ventricle is triangular in shape. Its upper surface is round, forming the larger part of the front of the heart. Its under surface is flat and adjacent to the diaphragm. It forms a small part of the back of the heart. The right ventricle walls are almost 1/3 as thin as those of the left ventricle. Its walls are thicker at its base and thinner towards the apex. The right ventricle cavity is the same size as the left ventricle with the ability to hold three fluid ounces.

Left
Ventricle
The
left ventricle is longer than the right ventricle, and it is shaped like a cone.
If looked at from the back, the cavity forms an oval outline. Contrary to that
of the right ventricle, the left ventricle forms a small part of the front of
the heart and a large part of the back. The left ventricle also forms the apex
of the heart. As mentioned above, the left ventricle’s walls
are three times thicker than the right ventricle’s. Also, the left ventricle’s
walls are thicker towards the apex
and thinner towards the base.
