Final answer:
Something 'squamous' in anatomy refers to a flat, scale-like surface, found in cells that form coverings or linings in the body, such as in the lungs or on protective surfaces.
Step-by-step explanation:
Based on how the term is used in anatomy, something that is described as "squamous" would be characterized as having a flat, irregular shape, similar to scales. The term squamous epithelial cells refers to cells that are typically round, flat, and possess a small, centrally located nucleus. These cells have slightly irregular outlines and fit together snugly to create a covering or lining for surfaces in the body. An example of squamous cells in action is their role in facilitating diffusion within the lungs for gas exchange and in blood capillaries for the exchange of nutrients and waste. When these cells are layered, as in stratified squamous epithelium, they provide protection for tissues that experience abrasion, such as skin, and linings of the mouth and vagina.
