The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding ADH**: ADH stands for Antidiuretic Hormone. It is produced in the hypothalamus and released into the bloodstream from the posterior pituitary gland. 2. **Function of ADH**: The primary function of ADH is to promote water reabsorption in the kidneys. It acts on the collecting ducts of the nephrons, making them more permeable to water. 3. **Water Reabsorption**: When ADH is present, more water is reabsorbed back into the bloodstream, which helps to maintain the body’s water balance and prevents dehydration. 4. **Impact on Blood Pressure**: By reabsorbing water, ADH helps to increase blood volume, which in turn can help maintain or increase blood pressure. 5. **Evaluating Options**: In the context of the question, we need to identify which statement correctly describes the role of ADH. The option stating "increased water absorption" aligns with the function of ADH. 6. **Conclusion**: Therefore, the correct answer regarding the function of ADH is the option that states it leads to increased water absorption. ---

In the following questions , a statement of assertion (A) is followed by a statement of reason (R). A: ADH response is observed during increased osmolarity due to dehydration. R : Vasopressin promotes water uptake from collecting ducts and DCT.

How many of the given statements are correct? A. Hypothalamus is the centre for eating and drinking. B. Corpus callosum is made up of nerve fibres. C. ADH is synthesized by the posterior pituitary. D. Balancing by semicircular canals is done by the macula.

Assertion: Vasopressin is also called anti-diuretic hormone (ADH) Vasopressin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces the loss of water through urine (diuresis).
