Answer: Bowman's capsule.
- A Bowman's capsule
- B the loop of Henle
- C the collecting duct
- D the ureter
Correct answer: A. Bowman's capsule
Explanation: Bowman's capsule collects the filtrate from the glomerulus.
Filtrate flows through four functionally distinct stages of the nephron: Bowman's capsule filters blood, the PCT reabsorbs most useful substances unconditionally, the Loop of Henle builds a concentration gradient via counter-current exchange, the DCT secretes selected substances, and the collecting duct performs the final ADH-controlled water reabsorption.
Concept context
Nitrogenous waste, kidney structure, urine formation in the nephron, and hormonal regulation of excretion.
