Answer: The three types of muscle tissue are skeletal,
cardiac and smooth. Skeletal muscle is attached to bones
and is responsible for voluntary movements. Cardiac
muscle is found in the heart and pumps blood throughout
the body. Smooth muscle is found in the walls of hollow
organs and vessels and helps regulate involuntary functions
such as digestion, blood pressure and breathing.
