Question:
Angiotensin is produced by
Angiotensin is produced by
Show Hint

- Liver
- Heart
- Pituitary gland
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding renin-angiotensin system.
The renin-angiotensin system regulates blood pressure and fluid balance in the body. It involves multiple organs including kidney and liver.
Step 2: Role of liver.
The liver produces angiotensinogen, an inactive plasma protein. This is the precursor molecule required for formation of angiotensin.
Step 3: Activation process.
Renin released from kidney converts angiotensinogen into angiotensin I. Further conversion leads to angiotensin II, the active form.
Step 4: Physiological role.
Angiotensin II causes vasoconstriction and increases blood pressure. It also stimulates aldosterone secretion.
Step 5: Evaluation of options.
Kidney produces renin, heart is not involved in production, and pituitary gland secretes hormones unrelated to this pathway.
Step 6: Final conclusion.
Thus, angiotensin (via angiotensinogen precursor) is produced by the liver.
