Cuboidal cells are characterized by their cube-like or hexagonal shape, typically having a roughly equal height, width, and depth. They are commonly found in glandular tissues, where they function in secretion and absorption. For example, the lining of the kidneys and certain glands are primarily composed of cuboidal epithelium. This specific shape allows for a greater volume of cytoplasm, which contributes to their function in processes that require a higher metabolic activity and substance transport.

The other types of epithelial cells have distinct shapes that support their unique functions. Squamous cells are thin and flat, which facilitates processes like diffusion and filtration. Columnar cells are taller and resemble columns, making them suitable for absorption and secretion in areas such as the digestive tract. Transitional cells have an ability to change shape, which is essential for accommodating fluctuating volumes in organs like the bladder. Understanding these differences in epithelial cell shapes helps clarify their roles within various tissues and organs.
