Smooth muscle wraps around respiratory bronchioles and can change the diameter of the airway. Skeletal muscle is not present in the respiratory system, cardiac muscle is found in the heart, and voluntary muscle refers to skeletal muscle that is under conscious control. Respiratory muscle refers to the diaphragm and other muscles involved in breathing.
