Question

What are the special functions of cardiac muscles? (At least 4)

Answer 1

Function of cardiac muscles are:

To control contraction and relaxation of heart during blood circulation.

Cardiac muscles is a type of tissue which is found only in heart. This muscle allow our heart to pump blood which moves through our circulatory system and it is an involuntary action.

Contraction and relaxation of heart occurs with the help of cell called pacemaker cell which receives a signal form nervous to control the heart rate. This pacemaker cell is connected with cardiac muscles.

Answer 2

Answer:

Explanation:

The primary function of the cardiac muscle is to regulate the functioning of the heart by the relaxation and contraction of the heart muscles. Other functions of cardiac muscles include:

• The cardiac muscles function as the involuntary muscle.
• The cardiac muscles are also involved in the movement or the locomotion.
• The cardiac muscles work without stopping, day and night. They work automatically and make the heart contract so that the heart can squeeze the blood vessels and release so that the heart can fill up with blood again.
• The heart comprises a specialized type of cardiac tissue, which consists of “pacemaker” cells. These contract and expand in response to electrical impulses from the nervous system.
