What is the primary function of sudoriferous glands?

• A. To produce melanin for skin color
• B. To excrete perspiration and regulate body temperature
• C. To stimulate collagen production
• D. To provide elasticity to skin

Answer: (B)

Sudoriferous glands, commonly known as sweat glands, primarily function to excrete perspiration, which plays a crucial role in regulating body temperature. When the body temperature rises due to environmental heat or physical activity, these glands produce sweat that is released onto the surface of the skin. As this sweat evaporates, it effectively cools the skin and the underlying tissues, helping to maintain homeostasis and prevent overheating.

This process of thermoregulation is vital for bodily functions, especially in warm conditions or during intense physical exertion. Furthermore, the sweat produced by these glands also assists in excreting certain waste products, such as salts and urea, but its primary and most critical role remains in temperature regulation. Other functions associated with skin, like melanin production or collagen stimulation, are not related to the activity of sudoriferous glands.
