The relationship of structure and function is one of the major themes in biology. For the following tissue type, describe the structure of the cells and tissue, identify a part of the digestive tract that contains this tissue, and then explain how the function is related to the structure.

- cuboidal epithelial tissue

Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal cells. These cuboidal cells have large, spherical and central nuclei. This type of tissue is found lining parts of organs and ducts in the body. its structure allows for absorption and diffusion in those areas. Mostly found in organs that are specialized for secretion, such as salivary glands (part of the digestive tract) and thyroid follicles, and those that are specialized for diffusion, such as the kidney tubules.
