Answer:

The intercalated discs allow the cardiac muscle fibers to contract in unison, producing a uniform contraction of the heart. If they were not functional, the cardiac muscle cells would not contract in unison and the heart would not have uniform, functional contractions.

I hope this answer helps you out! :D

The heart is a muscular organ, which is made up of blood vessels, and cardiac muscles. The cardiac muscle if not working properly will lead to heart failure or heart attack.

The functions of cardiac muscles include:

  • The cardiac muscles are involuntary, uninucleate, and branched. The muscles undergo rhythmic contractions to pump blood.

  • The cardiac muscle constitutes the pacemaker cells, which stimulate the contraction of the heart.

  • In case of failure of cardiac muscle, will not produce rhythmic contractions, and would lead to heart failure. The muscles are involuntary and could not be controlled.

Thus, the cardiac muscle plays a crucial role in the contractions of the heart, and the failure of muscle would lead to a heart attack.
