Final answer:
The analogy compares the hormones prolactin and vasopressin, produced by the pituitary gland with distinct functions; prolactin stimulates milk production, whereas vasopressin regulates blood pressure through water reabsorption by the kidneys.
Step-by-step explanation:
The correct answer to the question PRL is to ________ as ADH is to ________ is D- prolactin; vasopressin. This analogy refers to the hormones produced by the pituitary gland and their functions. Prolactin (PRL) is the hormone produced by the anterior pituitary that is responsible for stimulating milk production after childbirth. Vasopressin, also known as antidiuretic hormone (ADH), regulates blood pressure by adjusting the water reabsorbed by the kidneys, playing a role in maintaining homeostasis in body water. In this context, gonadotropins, oxytocin, and cortisol are not directly related to the function represented by PRL and ADH.
