Answer:
2. muscular tissue.
Step-by-step explanation:
The muscular tissue is responsible for the movement of the body, body parts, and organs. About 40% of our body is formed of muscles. The muscle tissue is made up of highly contractile muscle fibers.
There are 3 types of muscular tissues - skeletal muscle / voluntary muscle, smooth muscle / involuntary muscle, cardiac muscle.
Skeletal muscles are striped in appearance and hence called as striated muscles. Their muscle activities are under the control of an individual's will. Therefore, these muscles are known as voluntary muscle.
The second type of muscular tissue is smooth muscle. These are located in the inner wall of visceral organs such as the GI tract, reproductive organs, etc. They are smooth in appearance, hence known as smooth muscle. These muscles are not under the control of one's will. Hence it is called involuntary muscle.
The third type of muscle is cardiac muscle. It is exclusively present in the heart. Many cardiac muscle cells are arranged in branches to form a cardiac muscle.
