- Mucosa: Innermost layer, composed of epithelial cells, rich in blood vessels, and highly sensitive.
- Adventitia: Middle layer, composed of connective tissue, containing blood vessels and nerve endings.
- Muscularis: Outermost layer, composed of smooth muscle, responsible for involuntary muscle contractions.
