Explanation:
Detailed explanation-1: -The cardiac muscle is responsible for the contractility of the heart and, therefore, the pumping action. The cardiac muscle must contract with enough force and enough blood to supply the metabolic demands of the entire body. This concept is termed cardiac output and is defined as heart rate x stroke volume.
Detailed explanation-2: -The cells of cardiac muscles are cylindrical, branched, and uni-nucleate. Cardiac muscles are involuntary muscles that contract rapidly but do not get fatigued. They control the contraction and relaxation of the heart.
