The lamina propria is a layer of loose connective tissue that lies directly beneath the epithelium in the mucosa of the digestive tract. It contains the capillaries that nourish the epithelium and absorb digested nutrients. The submucosa is a layer of dense connective tissue that lies beneath the mucosa and contains larger blood vessels, lymphatic vessels, and glands. The serosa is a layer of connective tissue that covers the outer surface of some parts of the digestive tract, whereas the adventitia is a layer of connective tissue that covers the outer surface of other parts of the digestive tract.
