ADH helps in water elimination, making the urine hypotonic.

AI Generated Solution

The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding ADH**: The Anti-Diuretic Hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and stored in the posterior lobe of the pituitary gland. 2. **Function of ADH**: When released into the bloodstream, ADH acts primarily on the kidneys. Its main role is to promote the reabsorption of water from the filtrate in the kidney tubules back into the bloodstream. 3. **Effect on Urine Concentration**: By facilitating water reabsorption, ADH decreases the amount of water excreted in urine. This results in urine that is more concentrated, meaning it has a higher solute concentration and is therefore considered hypertonic, not hypotonic. 4. **Conclusion**: The statement "ADH helps in water elimination, making the urine hypotonic" is false. Instead, ADH helps in conserving water, leading to the production of concentrated urine. **Final Answer**: The statement is false. ADH helps in the conservation of water, leading to the production of hypertonic urine. ---
