Which of the following statements is true?
A) Most filtrate (99%) is eliminated as urine.
B) Normal filtrate contains a large amount of protein.
C) Reabsorption of water in the filtrate may be hormonally controlled.
D) Sodium ions are secreted into the filtrate of the proximal convoluted tubule.
E) Hormones play a minor role in fluid homeostasis.
Filtrate
The liquid that has passed through a filter, often referring to the fluid that passes through the kidney's nephrons during the process of urine formation.
Hormonally Controlled
Describes processes or activities in the body that are regulated by hormones, substances secreted by glands for regulating bodily functions.
Sodium Ions
Positively charged ions of sodium (Na+), essential for various physiological functions including the regulation of blood pressure and volume.
- Expound on the methodology and importance of tubular reabsorption and secretion in ensuring homeostasis.
- Discuss the variables that determine the osmolality and volume of urine.

Final Answer :
C
Explanation :
Reabsorption of water in the filtrate is indeed hormonally controlled, primarily by antidiuretic hormone (ADH) and aldosterone, which regulate water and sodium reabsorption, respectively, to maintain fluid balance and blood pressure.
