A. Glomerular capsule → Proximal convoluted tubule → Loop of Henle → Collecting duct → Distal convoluted tubule
B. Glomerular capsule → Loop of Henle → Proximal convoluted tubule → Distal convoluted tubule → Collecting duct
C. Glomerular capsule → Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Collecting duct
D. Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Glomerular capsule → Collecting duct
QUESTION 9
Which if any is NOT an accurate pairing of a key excretory function with its definition?
A. Secretion: modifies the filtrate within the proximal and distal tubules by adding solutes.
B. Filtration: water, nitrogenous waste, and valuable solutes are forced from the blood into the nephron's proximal tubule.
C. Excretion: moves urine, the processed filtrate, out of the kidney, through the ureter, the bladder, and finally out of the body via the urethra.
D. Reabsorption: transports certain toxins, drugs, and excessive ions from the capillaries to the filtrate.
