Multiple Choice

Which of the following is NOT a function of smooth muscle?

Pumping blood throughout the body

Regulating the diameter of blood vessels

Moving food through the digestive tract

Controlling airflow in the respiratory passages

Verified step by step guidance

Step 1: Understand the characteristics of smooth muscle. Smooth muscle is an involuntary, non-striated muscle type found in various organs and structures such as blood vessels, the digestive tract, and respiratory passages. It is responsible for functions like regulating vessel diameter, moving food, and controlling airflow.

Step 2: Analyze the functions listed in the question. Smooth muscle is involved in regulating the diameter of blood vessels (vasoconstriction and vasodilation), moving food through the digestive tract (peristalsis), and controlling airflow in respiratory passages (bronchoconstriction and bronchodilation).

Step 3: Consider the function of pumping blood throughout the body. This is primarily the role of cardiac muscle, which is a specialized striated muscle found in the heart. Cardiac muscle contracts rhythmically to pump blood, a function distinct from smooth muscle.

Step 4: Compare the functions of smooth muscle with the listed options. Identify which function does not align with the known roles of smooth muscle.

Step 5: Conclude that the function 'Pumping blood throughout the body' is not a role of smooth muscle, as this is the responsibility of cardiac muscle.
