D

Verified step by step guidance
1
Step 1: Understand the types of muscle tissue in the human body: skeletal, cardiac, and smooth muscle.
Step 2: Recognize that skeletal muscle is primarily responsible for voluntary movements and is attached to bones.
Step 3: Know that cardiac muscle is found only in the heart and controls involuntary contractions to pump blood.
Step 4: Identify smooth muscle as the type of muscle tissue found in the walls of hollow organs, including the digestive tract, where it controls involuntary movements such as peristalsis.
Step 5: Conclude that smooth muscle is the correct answer because it regulates involuntary contractions in the digestive system, enabling processes like peristalsis.
