10. Functions of the nephron include all of the following except

A. Reabsorption of urea nitrogen B. Fluid homeostasis C.Maintaining electrolyte balance
D.Regulation of blood pressure
E. Maintaining blood pH

I think A but really stuck between A & B

To determine the correct answer, let's analyze the functions listed and eliminate the options that are incorrect.

A. Reabsorption of urea nitrogen: This is a function of the nephron. Urea nitrogen is reabsorbed in the proximal convoluted tubule of the nephron.

B. Fluid homeostasis: This is also a function of the nephron. The nephron plays a crucial role in regulating the volume and concentration of fluids in the body.

C. Maintaining electrolyte balance: This is another function of the nephron. The nephron helps regulate the levels of electrolytes, such as sodium, potassium, and calcium, in the body.

D. Regulation of blood pressure: This is a correct function of the nephron. The nephron contributes to the regulation of blood pressure by controlling the balance of water and salt in the body.

E. Maintaining blood pH: This is also a function of the nephron. The nephron helps regulate the pH of the blood by controlling the excretion of hydrogen ions (acidic) and reabsorption of bicarbonate ions (basic).

Now, let's review the options:

A. Reabsorption of urea nitrogen: Correct
B. Fluid homeostasis: Correct
C. Maintaining electrolyte balance: Correct
D. Regulation of blood pressure: Correct
E. Maintaining blood pH: Correct

Based on our analysis, all options correctly state the functions of the nephron. Therefore, the answer is none of the above (option F: All of the functions listed are performed by the nephron).
