Practice question

Pick B: V2 receptors via cAMP. Thinking about Endocrinology in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: V2 receptors via cAMP is the option that correctly names the structure, process, or principle asked for in Endocrinology. Hence V2 receptors via cAMP is correct. Treat this as a building block for the rest of Endocrinology; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
