Which of the following actions corresponds to cuboidal epithelium?

Which of the following actions corresponds to cuboidal epithelium?

• A. Secretion
• B. Absorption
• C. Diffusion
• D. Protection

Answer: (A)

Cuboidal epithelium is primarily specialized for secretion. This type of epithelial tissue is composed of cube-shaped cells, which are often found in glands, such as the salivary glands, pancreas, and sweat glands. The structure of cuboidal cells allows for the efficient production and release of various substances, including hormones and enzymes. Their relatively large size compared to other types of epithelial cells enables them to house more organelles involved in the synthesis and secretion processes. While cuboidal epithelium can also contribute to absorption and, to a lesser extent, protection, these are not its primary functions. Absorption is more characteristic of columnar epithelium, particularly in the digestive tract, where taller, columnar cells optimize for nutrient uptake. Similarly, protection is typically associated with stratified epithelium, which is designed to cover and protect underlying tissues effectively. Thus, the action that directly corresponds to cuboidal epithelium is primarily related to secretion.
