Which type of gland is responsible for secretion through ducts?

The correct answer, exocrine glands, are specifically designed to secrete their products through ducts to an external surface or into a body cavity. These glands play a crucial role in numerous bodily functions, such as digestion and temperature regulation. An example of exocrine glands includes sweat glands, salivary glands, and the sebaceous glands in the skin, which deliver their secretions directly to the external environment.

In contrast, endocrine glands, which are another type of gland, release their products—hormones—directly into the bloodstream without the use of ducts. This allows them to have widespread effects throughout the body rather than localized action.

Apocrine and merocrine glands are both classifications of exocrine glands based on their method of secretion. Apocrine glands release their secretion along with a portion of cytoplasm from the cell, such as in the case of certain sweat glands. On the other hand, merocrine glands secrete their products directly through the cell membrane without any loss of cellular material, as seen in salivary glands. Thus, while both apocrine and merocrine glands are exocrine in nature, the primary distinction lies in their specific mechanisms of secretion, each still functioning under the
