* Sweat glands: These glands release sweat onto the skin's surface. As sweat evaporates, it takes heat with it, cooling the body.

* Thyroid gland: This gland produces thyroid hormone, which increases metabolism and heat production.

* Adrenal glands: These glands release adrenaline, which also increases metabolism and heat production.

While not technically glands, the following also play a crucial role in thermoregulation:

* Hypothalamus: This region of the brain acts as the body's thermostat, sensing changes in body temperature and sending signals to other organs to adjust accordingly.

* Blood vessels: Blood vessels can dilate to release heat or constrict to conserve heat.

It's important to note that thermoregulation is a complex process involving multiple organ systems, not just glands. The skin, muscles, and nervous system all play important roles as well.
