MH 070 Heart

Right & Left Ventricles

The right and left ventricles are on the high pressure side of the heart. The higher workload results in thicker walls than in the atria (compare with MH 069 Heart).

Right Ventricle - receives blood from the right atrium and pumps it into the lungs via the pulmonary arteries.

Heart wall is divided into three parts:

Endocardium - inner surface of endothelial cells supported by only a few connective tissue fibers
Myocardium - cardiac muscle responsible for the pumping action of the heart. It also contains blood vessels, nerves and adipose cells.
Epicardium - outer surface of mesothelial cells (missing on this specimen) supported by dense irregular connective tissue

Left Ventricle - receives oxygenated blood from the left atrium and pumps into the systemic circulation via the aorta. This higher workload results in a much thicker wall than the right ventricle.

Heart wall is divided into three parts:

Endocardium - inner surface of endothelial cells supported by only a few connective tissue fibers
Myocardium - the thickest of the four chamber of the heart
Epicardium - outer surface of mesothelial cells (missing from this specimen) supported by a layer of dense irregular connective tissue. An inner layer of loose adipose connective tissue is particularly prominent.
