Final answer:
Muscle tissues in the human body consist of skeletal, cardiac, and smooth muscle, each fulfilling different functions. Skeletal muscles enable voluntary movements like walking, whereas cardiac muscle pumps blood and smooth muscle facilitates involuntary processes such as digestion and respiration.
Step-by-step explanation:
The human body consists of three types of muscle tissues: skeletal muscle, cardiac muscle, and smooth muscle. Each type of muscle tissue serves its distinct functional need.
Skeletal Muscle
Skeletal muscle tissue is responsible for movement such as walking. These muscles are under voluntary control, meaning they contract when we decide to move. For instance, when you want to lift your arm, your brain sends a signal that causes the skeletal muscles in your arm to contract, raising it.
Cardiac Muscle
The cardiac muscle tissue is found in the heart. It is specialized to pump blood continuously throughout the body. Unlike skeletal muscle, the contraction of cardiac muscle is not under voluntary control; it beats automatically in a rhythmic pattern.
Smooth Muscle
Smooth muscle tissue lines various organs and is involved in involuntary movements. It facilitates bodily processes such as digestion, by moving food through the digestive system, and respiration, by aiding in the contraction and expansion of the lungs.
