Verified step by step guidance

Step 1: Understand the types of muscle tissue. There are three main types of muscle tissue in the human body: skeletal muscle, cardiac muscle, and smooth muscle. Each type has distinct characteristics and functions.

Step 2: Recall the function of smooth muscle. Smooth muscle is involuntary and non-striated, meaning it does not have the banded appearance seen in skeletal and cardiac muscle. It is primarily responsible for movements in internal organs, such as the digestive tract, blood vessels, and respiratory pathways.

Step 3: Compare the other muscle types. Skeletal muscle is voluntary and striated, used for movement of bones and body parts. Cardiac muscle is striated and involuntary, found only in the heart. Striated muscle is another term for skeletal or cardiac muscle, depending on the context.

Step 4: Relate smooth muscle to the digestive tract. The walls of the digestive tract contain smooth muscle, which contracts rhythmically to propel food through the system in a process called peristalsis.

Step 5: Conclude that smooth muscle is the correct answer based on its location and function in the digestive tract.
