Final answer:
The hypothalamus plays a role in regulating water balance in the body through osmoreceptors and the release of antidiuretic hormone (ADH) to conserve water.
Step-by-step explanation:
True. The hypothalamus plays a crucial role in regulating water balance in the body. It contains osmoreceptors that monitor the concentration of solutes in the blood. If the blood osmolality increases above its ideal value, the hypothalamus transmits signals that result in a conscious awareness of thirst, triggering the person to drink water.
In addition, the hypothalamus releases antidiuretic hormone (ADH) through the posterior pituitary gland to signal the kidneys to recover water from urine, effectively diluting the blood plasma and conserving water.
