The Cardiac Skeleton Reinforces the Valves and Helps Prevent Overexpansion

Question

The cardiac skeleton reinforces the valves and helps prevent overexpansion of the heart.

Accepted Answer

The cardiac skeleton, also known as the fibrous skeleton of the heart, forms a rigid framework that supports the heart's valves and myocardium. It helps prevent overexpansion of the heart and ensures coordinated contraction of the cardiac muscle fibers.
