What is the function of sudoriferous glands?

1. Produce oil

2. Secrete wax

3. Regulate temperature through sweat

4. Support tissue structure

The correct answer is: Regulate temperature through sweat

Sudoriferous glands, commonly known as sweat glands, serve a critical role in thermoregulation by producing sweat. When the body heats up, whether due to exercise or external temperature, these glands are stimulated to secrete sweat onto the surface of the skin. The evaporation of sweat from the skin surface leads to cooling, which helps maintain the body’s optimal temperature. This process is vital for preventing overheating and managing body temperature during physical exertion and heat exposure. The other functions mentioned—producing oil, secreting wax, and supporting tissue structure—are not associated with sudoriferous glands. Instead, sebaceous glands are responsible for producing oil, ceruminous glands secrete wax, and various connective tissues provide structural support. Understanding the specific function of sudoriferous glands in thermoregulation highlights their importance in maintaining homeostasis within the body.
