What is the primary function of eccrine glands?

1. Secretion of oil

2. Production of sweat

3. Regulation of temperature

4. Hydration of skin

The correct answer is: Production of sweat

Eccrine glands primarily function in the production of sweat, which plays a vital role in the body's thermoregulation. These glands are located throughout the body, particularly on the palms, soles of the feet, and forehead. When the body temperature rises due to exercise, heat, or external temperature, eccrine glands secrete a watery solution (sweat) onto the skin's surface. As this sweat evaporates, it cools the skin and helps maintain a stable internal body temperature. While temperature regulation is indeed an important aspect of eccrine gland function, the primary role focuses specifically on sweat production. This response helps to convey how the body's system works to prevent overheating and maintain homeostasis. Other glands, such as sebaceous glands, are responsible for oil secretion, while hydration of the skin is typically managed through various mechanisms, including natural oils and external moisturizers, rather than directly by eccrine glands.
