Question

Where is angiotensinogen secreted from in the human body?

• A. Kidney
• B. Pancreas
• C. Liver
• D. Spleen

Hint:

Angiotensinogen is produced in the liver, while renin is released from the kidneys. Together they initiate the renin–angiotensin system that regulates blood pressure.

Answer 1

The Correct Option is C

To answer the given question about the secretion of angiotensinogen in the human body, let's discuss the role and secretion site of angiotensinogen.

Angiotensinogen: This is a protein produced and secreted by the liver. It is the precursor to angiotensin I, which is involved in the body’s blood pressure regulation mechanism.

Secretion Site: The liver produces and releases angiotensinogen into the bloodstream. Once in the bloodstream, it interacts with the enzyme renin (secreted by the kidneys) to form angiotensin I, which is later converted into angiotensin II.

Now, let’s analyze each option:

• Kidney: The kidneys secrete renin, not angiotensinogen. Thus, this option is incorrect.
• Pancreas: The pancreas releases digestive enzymes and hormones like insulin and glucagon, but not angiotensinogen. Thus, this option is incorrect.
• Liver: This is the correct option, as the liver is responsible for secreting angiotensinogen.
• Spleen: The spleen is involved in filtering blood and is not known for secreting angiotensinogen. Thus, this option is incorrect.

Conclusion: The organ responsible for secreting angiotensinogen in the human body is the liver, making option 'Liver' the correct answer.
