Examples
- Cardiac muscle is the muscle tissue of the heart that allows it to beat continuously throughout one's life.
- In cardiac muscle, the muscles are able to contract and relax repeatedly without getting tired due to the unique structure of the muscle fibers.
- Cardiac muscle cells do not tire because of the large amount of mitochondria that provide energy to support continuous contraction and relaxation.
- Cardiac muscle fibers are specially designed to be highly contractile, allowing the rapid contraction necessary for effective pumping of the blood through the circulatory system.
- The contraction and relaxation of cardiac muscle enable the heart to pump blood throughout the body efficiently.
