Final answer:
The gut immune system consists of components such as MALT and Peyer's patches that protect the gastrointestinal tract. It includes epithelial cells, dendritic cells, and T cells that play important roles in immune surveillance and response.
Step-by-step explanation:
The gut immune system consists of several components that work together to protect the gastrointestinal tract. One important component is the mucosa-associated lymphoid tissue (MALT), which is a collection of lymphatic tissue that lines the mucosa throughout the body. MALT acts as the immune barrier and response in areas of the body with direct contact to the external environment. Another component is the Peyer's patches, which are small aggregates of lymphoid tissue in the ileum that detect pathogens in the intestines and induce an immune response. Additionally, the gut immune system includes epithelial cells, dendritic cells, and T cells that play crucial roles in immune surveillance and response.
