The ileum is the final section of the small intestine, located between the jejunum and the large intestine. It is lined with a layer of mucous membrane, which plays a crucial role in the digestive process.
The mucous membrane in the ileum consists of several layers. The innermost layer is the epithelium, which is composed of specialized cells called enterocytes. These cells have microvilli on their surface, which increase the surface area available for absorption of nutrients.
Beneath the epithelium is the lamina propria, a layer of loose connective tissue. It contains blood vessels, lymphatic vessels, and immune cells, which help in the absorption of nutrients and provide defense against pathogens.
The next layer is the muscularis mucosae, which consists of smooth muscle fibers. These muscles contract and relax to facilitate the movement of food and aid in the absorption process.
Finally, the outermost layer is the submucosa, which is a thicker layer of connective tissue. It contains blood vessels, nerves, and lymphatic vessels, which supply nutrients and oxygen to the mucous membrane and help in the regulation of digestion.
Overall, the layer of mucous membrane in the ileum is highly specialized for the absorption of nutrients. The presence of microvilli, blood vessels, and lymphatic vessels allows for efficient absorption, while the immune cells provide protection against pathogens.
