| Assertion (A): | Endocrine glands pour/release their secretion directly in blood | 
| Reason (R): | These glands are also known as paracrine glands | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |

| 4. | Both (A) and (R) are false. | 
| Assertion (A): | Gonadotrophins stimulate the release of FSH and LH from anterior pituitary | 
| Reason (R): | LH and FSH do not stimulate gonadal activity | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| Assertion (A): | Vasopressin is also known as anti-diuretic hormone | 
| Reason (R): | Vasopressin stimulates the reabsorption of water by distal tubules of nephron and prevents diuresis | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| Assertion (A): | PTH and thyrocalcitonin are antagonistic hormones | 
| Reason (R): | PTH is produced by the parathyroid gland while thyrocalcitonin is produced by thyroid gland | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). | 
| 3. | (A) is true but (R) is false. | 
| 4. | Both (A) and (R) are false. | 
| Assertion (A): | Aldosterone helps in the maintenance of electrolyte balance and body fluid volume | 
| Reason (R): | Aldosterone stimulates the reabsorption of \(K^+\) and \(PO^{2-}_4\) ions from DCT | 
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). | 
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |

| 4. | Both (A) and (R) are false. | 
| Assertion (A): | Glucagon is a hyperglycemic hormone | 
| Reason (R): | Glucagon reduces the cellular glucose uptake and utilisation thereby increasing blood sugar level |
