Which glands are responsible for regulating body temperature and eliminating waste products?

The correct choice for the glands responsible for regulating body temperature and eliminating waste products is the sudoriferous glands, commonly known as sweat glands. These glands play a crucial role in thermoregulation by producing sweat, which cools the body when it evaporates from the skin's surface. As the body heats up due to physical activity or environmental conditions, these glands become active, releasing sweat to maintain a stable internal temperature.

In addition to their role in temperature regulation, sweat glands also help eliminate certain waste products from the body, such as urea and salts, through perspiration. This dual function highlights the importance of these glands in both maintaining homeostasis and contributing to the body's waste management system.

The other glands listed, while important for various bodily functions, do not primarily serve the functions of temperature regulation and waste elimination in the same way.
