Question

multiple choice question
neurons in the ____ monitor the ____ balance of the blood, secreting adh when the blood is too concentrated.

hypothalamus; water - salt

anterior pituitary; calcium

kidneys; anterior pituitary

Explanation:

Neurons in the hypothalamus are responsible for monitoring the water - salt balance of the blood. When the blood is too concentrated (high salt concentration or low water content), the hypothalamus signals for the release of antidiuretic hormone (ADH). The anterior pituitary is not involved in directly monitoring blood balance in this way, and the kidneys are the target organs of ADH rather than the monitor of blood balance for ADH secretion initiation.

Answer:

hypothalamus; water - salt
