You have a bad reaction to a drug and destroy both your kidneys. How does this affect your aldosterone control of sodium?
A Not at all since aldosterone comes from your adrenal glands
B. It causes your lungs to produce more angiotensinogen
C. Quite a bit because it means you no longer can make renin
D. Not much, but it makes your potassium levels become the driving factor in respiration
The process of osmoregulation and excretion is conducted via excretory organs called kidneys. They originate from the mesomere of the embryo. Kidneys are located on either side of the dorsal aorta.
Answer and Explanation: 1
The correct option is C. Quite a bit because it means you no longer can make rennin.
Renin indirectly acts on regulating the aldosterone hormone to control sodium levels in the body. Renin acts on a protein called angiotensinogen secreted by the liver. Angiotensinogen converts into angiotensin I by the action of renin. Angiotensin I is inactive, and it changes into angiotensin II with the help of the angiotensin-converting enzyme. Angiotensin II directly influences the production of aldosterone from the adrenal gland.
- A. Not at all since aldosterone comes from your adrenal gland -- This option is incorrect because adrenal glands are located on the kidneys, and damage of kidneys also affects the glands.
- B. It causes your lungs to produce more angiotensinogen -- This option is incorrect because the liver produces angiotensinogen. Lungs' vascular endothelium consists of angiotensin-converting enzymes.
- d. Not much, because it makes potassium levels become the driving factor in respiration -- This option is incorrect because kidney failure rarely affects the lungs. However, it can cause problems in the lungs by disturbing the renal acid-base balance.

Adrenal glands are endocrine organs that secrete hormones into the bloodstream. The adrenal cortex is the outer part of the glands, which secretes steroid hormones, including mineralocorticoids. Learn about the main mineralocorticoid - aldosterone, the role that aldosterone plays in the renin-angiotensin system, and how aldosterone regulates sodium, potassium and blood pressure in the body.
