Aldosterone increases blood pressure mainly by:
Correct option is B, Increasing Na⁺ reabsorption. In Endocrinology, the accurate description is Increasing Na⁺ reabsorption, and that is what you should commit to memory. Keep the definition tight and the role clear — the functional job described in the stem is exactly what Increasing Na⁺ reabsorption does in Endocrinology. Then Increasing Na⁺ reabsorption is the answer you can defend. Check yourself by covering the options and writing the answer first, then matching the letter — that builds confidence. If the wording feels dense, translate it into everyday language first, then map that plain sentence back onto Increasing Na⁺ reabsorption. Remember that physiology questions reward precise language: name the process, the location, and the outcome, then match that to the option text.
