Question

Name the plant and animal hormone on the basis of the function given below:

• Increases blood pressure to increase ultrafiltration……………
  

Answer 1

Ultrafiltration

Ultrafiltration is the process by which the nephron of the kidneys filters wastes products from the blood, which are then excreted via urine.

Renin:

1. The site of synthesis for renin is the kidneys.
2. If the systolic blood pressure is lower than 100mmHg, the kidneys release renin into the blood circulation.
3. The renin activates the angiotensin, which stimulates the release of the aldosterone hormone from the adrenal gland. The aldosterone then increases the blood pressure.
4. The increased blood pressure increases the ultrafiltration process by the nephrons.

Final Answer: The hormone that increases blood pressure to increase ultrafiltration is renin.
