Epithelial tissue can be found in the lining of internal organs. certain types of epithelial tissue are only one cell thick. these cells also tend to have a large surface area. these qualities make it easy for substances to enter the epithelial tissue. based on the passage above, why would epithelial tissues be found in organs that are involved in absorption, such as the small intestine?

Tissues may be defined as the group of similar cells that combine together to form a similar functions. Four main types of tissues are epithelial tissue, connective tissue, muscle tissue and  nervous tissue.

Epithelial tissue are presents on the surface, body lining and lining of mouth and internal organs. The cells of epithelial tissue are one layer thick only. This means epithelial tissue that have the function of absorption are usually thick and has the large surface area that increases the rate of absorption.
