Question

Quizplus · Accepted Answer

The pericardium is a tough, fibrous sac that surrounds and supports the heart. It helps to protect the heart from trauma, infection, and other diseases. It also contains a small amount of fluid that helps the heart move more smoothly within the chest.

The chordae tendineae are thin, string-like structures that connect the heart valves to the muscles of the heart. They help to anchor the valves in place and prevent them from flipping back into the atria.

The myocardium is the muscular wall of the heart that contracts and pumps blood throughout the body.

The endocardium is the thin, smooth lining of the heart chambers and valves. It helps to reduce friction as blood flows through the heart.
