What is the difference between ADH and Vasopressin?
ADH and Vasopressin
ADH | Vasopressin |
| 1. Vasopressin, also known as antidiuretic hormone, is a hormone that helps to maintain osmolality (the concentration of dissolved particles in the serum, such as salts and glucose) and hence the volume of water in the extracellular fluid (the fluid space that surrounds cells). |
2. The volume and pressure of your blood increase as the concentration of water in your blood rise. Water metabolism is maintained by osmotic sensors and baroreceptors in conjunction with ADH. | 2. This is required to protect cells against rapid changes in water content, which can disrupt cell activity. |
3. These sensors and baroreceptors advise your kidneys to store or release water to maintain a healthy range of these substances when the particle concentration isn't balanced or blood pressure is too low. | 3. Vasopressin and oxytocin are both derivatives of a single primordial neurohypophyseal hormone known as vasotocin, which is found in lower vertebrates. |
