D) adrenal cortex
Solution
Answer Evaluation
-
Understanding the Question: The question asks where angiotensinogen is produced in the body. To answer this, we need to recognize the function and origin of angiotensinogen.
-
Analyzing the Options:
- A) Kidney: While the kidneys play a role in the renin-angiotensin system, they do not produce angiotensinogen.
- B) Liver: The liver is known to produce angiotensinogen, which is a precursor in the renin-angiotensin system.
- C) Lungs: The lungs do not produce angiotensinogen; they primarily convert angiotensin I to angiotensin II through the action of angiotensin-converting enzyme (ACE).
- D) Adrenal Cortex: The adrenal cortex produces aldosterone, but not angiotensinogen.
Summary Conclusion
The correct answer is B) liver, as the liver is the source of angiotensinogen in the body, which plays a crucial role in regulating blood pressure and fluid balance.
