Final answer:
The hypothalamus controls body temperature, water balance, and sleep.
Step-by-step explanation:
The hypothalamus controls several body functions, including:
- Body temperature: The hypothalamus acts as the body's thermostat, regulating and maintaining appropriate levels of body temperature.
- Water balance: It regulates the release of antidiuretic hormone (ADH) to control the reabsorption of water by the kidneys, helping maintain fluid balance.
- Sleep: Neurons within the hypothalamus regulate circadian rhythms, which are responsible for sleep-wake cycles.
