What is the function of a sweat gland?
To secrete perspiration
To produce antibiotics
To treat tuberculosis
To inhibit bacterial growth
The correct answer is: To secrete perspiration
The function of a sweat gland primarily revolves around secreting perspiration, which is essential for regulating body temperature and maintaining homeostasis. When the body's internal temperature rises, whether due to exercise or environmental heat, sweat glands release moisture onto the surface of the skin. As this moisture evaporates, it cools the body down, helping to prevent overheating. While sweat may have some antimicrobial properties that assist in inhibiting bacterial growth, the primary role of sweat glands is perspiration secretion. This process is vital for thermoregulation, hydration, and overall skin health. The other options do not accurately reflect the function of sweat glands, as they relate to different physiological processes not directly connected to perspiration.
