Which of the following is a function of the eccrine gland?

The function of the eccrine gland primarily involves regulating body temperature through perspiration. Eccrine glands are distributed widely across the skin and are most abundant on the forehead, palms, and soles of the feet. They are specialized for thermoregulation; when the body temperature rises, these glands produce a clear, odorless sweat composed mainly of water and electrolytes. This sweat evaporates from the skin's surface, which cools the body down and helps maintain a stable internal temperature.

In contrast, the other options refer to different functions that do not apply to eccrine glands. The production of sebum, for example, is a function of sebaceous glands, which are responsible for lubricating the skin and hair. The creation of sweat with a strong odor typically involves apocrine glands, which are located in areas like the axillae and groin and become active during emotional stress or physical activity. Lastly, while sweat can be produced in response to emotional stress, it is primarily the apocrine glands that are associated with this type of sweat, not the eccrine glands, which focus primarily on temperature regulation. Thus, the correct choice highlights the primary role of the eccrine glands in maintaining homeostasis through temperature control.
