The function of ADH, or Anti-diuretic hormone, is to inhibit water loss in the body. This hormone is produced in the hypothalamus and released by the posterior pituitary gland. Its main role is to regulate the body’s retention of water by acting on the kidneys. When ADH levels are high, it prompts the kidneys to reabsorb more water from the urine, thus reducing urine volume and conserving water in the body. This is particularly important in maintaining blood pressure and hydration levels.

In contrast, the other options do not accurately describe the primary role of ADH. Glycolysis is a metabolic process that breaks down glucose for energy, which is unrelated to the function of ADH. Muscle hypertrophy refers to the growth of muscle fibers and is influenced by factors such as exercise and hormones like testosterone, not ADH. Lastly, while heart rate can be affected by various hormones and physiological conditions, ADH does not directly increase heart rate; rather, it primarily focuses on water balance. Thus, the correct choice highlights the essential role of ADH in preventing excessive water loss.
