What role does muscle tissue play in the heart?

Answer 1

Cardiac muscle is the foundation of the heart. Cardiac muscle is an involuntary muscle meaning that it works on its own. You engage it like you would an arm or a let. The cardiac muscle has a built in system allowing it to be virtually fatigue resistant. This is because cardiac muscle is loaded with mitochondria which are a cell's power house or power plant.

Answer 2

The cardiac muscle in the heart is the musculature responsible for contracting the heart and thereby causing blood flow.

What the first answerer to this question wrote is more or less entirely inaccurate, especially the parts concerning proper blood-flow through the heart.

The correct order of blood flow is: Left atrium, left ventricle, aorta, peripheral arteries, arterioles (small arteries), capillaries, venules (small veins), veins, vena cava, right atrium, right ventricle, pulmonary system and back to left atrium.

The cardiac muscles found in the heart receives impulse from the brain then is used to pump deoxygenated blood from the right atrium, to the left ventricle, then to the pulmonary circulatory system, then to the left atrium, then to the left atrium, then finally the whole of the body through the aorta. It's special because the cardiac muscle can't experience tetanus, which is a condition where the muscle keeps constricting without dilating.

Answer 3

The muscle tissue plays a very significant role in the heart. The main function is the excitation-contraction coupling which enables the heart to pump blood.

Answer 4

The heart is a muscle, (myocardium), and the contraction of this muscle provides pressure to the blood to circulate around the body.
