Final answer:
The human body contains three types of muscle tissue: skeletal, which facilitates movement; cardiac, which pumps blood; and smooth, which is involved in involuntary functions like digestion.
Step-by-step explanation:
Types of Muscle Tissue
There are three types of muscle tissue found within the human body: skeletal muscle, cardiac muscle, and smooth muscle. Skeletal muscles are associated with the bones of the skeleton and facilitate movement. Cardiac muscle is found exclusively in the walls of the heart and is responsible for pumping blood throughout the circulatory system. Smooth muscle is found in various internal organs and is involved in numerous involuntary processes such as digestion and regulating blood flow.
All three muscle tissues are comprised of cells that have the unique ability to contract, which is critical for movement and various bodily functions. Key proteins involved in the contraction of these muscles include actin and myosin.
