ANATOMY

Detailed explanation-1: -Smooth muscle is responsible for the contractility of hollow organs such as blood vessels, the gastrointestinal (GI) tract, gall bladder, bladder, and uterus. The structure of smooth muscle differs greatly from that of skeletal muscle.

Detailed explanation-2: -Smooth muscle is a type of tissue found in the walls of hollow organs, such as the intestines, uterus and stomach. You can also find smooth muscle in the walls of passageways, including arteries and veins of de cardiovascular system.

Detailed explanation-3: -The mucosa, or mucous membrane layer, is the innermost tunic of the wall. It lines the lumen of the digestive tract. The mucosa consists of epithelium, an underlying loose connective tissue layer called lamina propria, and a thin layer of smooth muscle called the muscularis mucosa.

Detailed explanation-4: -Termed unitary smooth muscle or visceral muscle, this type of smooth muscle is the most common observed in the human body, forming the walls of hollow organs. Single-unit smooth muscle produces slow, steady contractions that allow substances, such as food in the digestive tract, to move through the body.

Detailed explanation-5: -Smooth muscle is the type of muscle tissue that lines the walls of internal organs such as the stomach, intestines and blood vessels. Digestion in the stomach is both chemical and mechanical.
