because the cardiac muscles are involuntary muscles (work automatically),

therefore the will always be working and never get tired.

involuntary muscles aree....

Smooth muscle or "involuntary muscle" is found within the walls of organs and structures such as the oesophagus, stomach, intestines, bronchi, uterus, ureters, bladder, and blood vessels.

Smooth muscle and cardiac muscle are actually two different things. Both are involuntary muscles but cardiac is striated and can sometimes be multinucleated whereas smooth muscle is always single nucleated and not striated.

What is a muscle found in the heart?

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.

What is the fuction of the cardiac cell?

Cardiac muscle cells are the cells that make up the cardiac muscle and help to pump blood through your heart. Each of these cells contain myofibrils which are the contractile units of muscle cells. These cells have the ability to produce ATP quickly, making them resistant to fatigue.


Compare and contrast skeletal cardiac and smooth muscles?

Cardiac muscle uses aerobic respiration which is rich in myoglobulin, glycogen, and very large mitochondria that fills over 25% of the cell. Skeletal muscle only 2% of the cell. In turn makes cardiac muscle highly resistant to fatigue.
