Vedclass · Answer

(B) Cardiac muscles are specialized muscles that form the contractile tissue of the heart.They are characterized by being involuntary,striated,and branched,allowing for coordinated contraction.Cardiac muscles never get fatigued primarily because they possess a very high density of $mitochondria$ to ensure a continuous supply of $ATP$ through aerobic respiration.Additionally,they receive a rich and constant blood supply,which provides the necessary oxygen and nutrients to sustain their continuous,rhythmic,and non-fatiguing activity throughout an individual's life.
