Smooth Muscle

Smooth muscle is a type of involuntary muscle found in many internal organs, such as the stomach, intestines, blood vessels, and urinary bladder. Unlike skeletal muscle, it isn’t under conscious control and works automatically to perform essential functions like moving food through the digestive system, regulating blood flow, and controlling the size of airways. Smooth muscle fibers are long, spindle-shaped cells that contract slowly and steadily. Their ability to sustain prolonged contraction is crucial for maintaining vital processes like blood pressure and digestion without tiring.
