What is Smooth muscle?

Smooth muscle is a type of muscle that is not under conscious control and is found in the walls of various organs and structures throughout the body, including the digestive system.

Smooth muscle contraction is slow and sustained, which is important in the digestive system as it helps to propel food through the digestive tract and allows for the mixing and churning of food with digestive enzymes and stomach acid.

Smooth muscle in the walls of blood vessels also helps to regulate blood pressure and flow. In the digestive system, smooth muscle is found in the walls of the esophagus, stomach, intestines, and other organs.

Contraction of the smooth muscle in these organs helps to propel food through the digestive tract, mix it with digestive enzymes and stomach acid, and facilitate the absorption of nutrients.

The contraction and relaxation of smooth muscle is controlled by the autonomic nervous system and various hormones.
