Question

the muscle found in the walls of most hollow organs of the body is
○ skeletal muscle.
○ smooth muscle.
○ involuntary striated muscle.
○ cardiac muscle.
○ voluntary striated muscle.

Explanation:

Skeletal muscle is attached to bones and is voluntary, so it's not found in hollow organ walls. Smooth muscle is involuntary and is located in the walls of most hollow organs (like the digestive tract, blood vessels, etc.). Involuntary striated muscle is cardiac muscle (which is only in the heart). Cardiac muscle is specific to the heart, not most hollow organs. Voluntary striated muscle is skeletal muscle. So the correct answer is smooth muscle.

Answer:

B. smooth muscle.
