Which skin appendages aid in cooling the body to prevent overheating on a hot day or during intense exercise? which skin appendages aid in cooling the body to prevent overheating on a hot day or during intense exercise? apocrine sweat glands ceruminous glands sebaceous glands eccrine sweat glands?

The correct answer is option (D) eccrine sweat glands.

Eccrine sweat glands are the major sweat glands found abundantly on the skin especially in palms, soles, head. They are involved in the secretion of a clear, sterile, odourless substance called the sweat. They are involved in the process of thermoregulation which is the ability of an organism to maintain a particular temperature irrespective of any temperature or changes in the environment.

During a hot day or intense exercise, the body temperature is maintained by the stimulation of the eccrine sweat glands by the nervous system to secrete water onto the surface of the body which gives a cooling effect by evaporation. Thus, the production of the eccrine sweat acts as a mechanism for temperature control.
