Step 1: Understand the types of muscle tissue in the human body: skeletal, cardiac, and smooth muscle.
Step 2: Recall that skeletal muscle is primarily attached to bones and is responsible for voluntary movements.
Step 3: Recognize that cardiac muscle is found only in the heart and is responsible for pumping blood.
Step 4: Identify that smooth muscle is found in the walls of hollow organs, including the digestive tract, and controls involuntary movements.
Step 5: Connect that smooth muscle moves food through the digestive tract by a process called peristalsis, which is a series of wave-like muscle contractions.
