Question

1) What is the function of the diffuse lymphatic tissue (Esophagus)?

2) Why is the epithelium stratified in the esophagus?

Answer 1

Answer;

1. Diffuse lymphatic tissue are cattered throughout the body such as in the connective tissue coats of the gastrointestinal, respiratory, and urogenital tracts. When noxious agents entering the body soon encounter them, lymphatic tissues helps prevent the injury from them and removal of these noxious agents from the body.

2. Stratified squamous epithelium is a type of tissue mostly found covering and lining parts of the body. In this tissue, cells are flattened, joined tightly together, and stacked. The major function of this tissue type is to provide protection, as it is found in areas that undergo wear-and-tear. The esophagus is the conduit that conducts food to stomach from pharynx. It can undergo wear and tear due to food bolus. hence It is lined by the stratified squamous epithelium
