After the process of filtration, the filtrate enters into the proximal convoluted tubule where most of the water, amino acids, and glucose are ____
|
|
stored in the bladder
|
|
|
excreted through the ureters
|
|
|
reabsorbed
|
|
|
concentrated in the urine
|
Explanation:
Detailed explanation-1: -The brush border and the extensive length of the proximal tubule dramatically increase the surface area available for reabsorption of substances into the blood enabling around 80% of the glomerular filtrate to be reabsorbed in this segment.
Detailed explanation-2: -Amino acids are reabsorbed from the tubular lumen by a saturable, carrier-mediated, concentrative transport mechanism driven by a Na+ electrochemical gradient across the luminal membrane.
Detailed explanation-3: -Around 67% of the sodium that gets filtered into the tubular fluid is reabsorbed in the proximal convoluted tubule, and the remaining 33% goes on to the rest of the nephron.
