Explanation:
Cardiac muscle is one of the three types of muscle which is present in the Heart of the organism.
The muscle fibres of the cardiac muscle possess a high amount of myoglobin- an Oxygen carrying molecule which can store the oxygen for some time.
The cardiac muscles have to pump blood in the body, for which they require a high amount of ATP, so they possess larger mitochondria.
