Identify the incorrect statement:
| 1. | An excessive loss of fluid from the body can activate the osmoreceptors which stimulate the hypothalamus to release antidiuretic hormone (ADH) or vasopressin from the neurohypophysis. |
| 2. | An increase in body fluid volume can switch off the osmoreceptors and suppress the ADH release. |
| 3. | ADH can also affect the kidney function by its dilatory effects on blood vessels. |
| 4. | An increase in blood pressure can increase the glomerular blood flow and thereby the GFR. |
