| CCK | Cholecystokinin or CCK acts on both pancreas and gall bladder and stimulates the secretion of pancreatic enzymes and bile juice, respectively. |
| GIP | GIP inhibits gastric secretion and motility by acting on the gastric glands. |
| ANF | The atrial wall secretes ANF. This opposes RAAS mechanism and reduces the blood pressure, as it is a vasodilator. |
| ADH | Secreted by neurohypophysis. ADH facilitates water reabsorption from latter parts of the tubule, thereby preventing diuresis. ADH can also affect the kidney function by its constrictory effects on blood vessels. |
