Question

What happen if the cardial muscles stop performing
rundomic contraction and relaxison in living body?​

Answer 1

Answer:

✒When a cardiac muscle cell contracts, the myosin filament pulls the actin filaments toward each other, which causes the cell to shrink. The cell uses ATP to power this contraction. A single myosin filament connects to two actin filaments on either side. This forms a single unit of muscle tissue, called a sarcomere ...

✒Contraction in cardiac muscle occurs due to the the binding of the myosin head to adenosine triphosphate ( ATP ), which then pulls the actin filaments to the center of the sarcomere, the mechanical force of contraction....

Answer 2

the cardiac muscles are present in the heart only it helps in contraction and relaxation of the heart thus help in pumping the blood if it stops functioning the the the blood will not be pumped into the body and no blood circulation would happen
