This structure is responsible for the largest portion of reabsorption:
|
|
loop of Henle
|
|
|
proximal convoluted tubule
|
|
|
distal convoluted tubule
|
|
|
Bowman’s capusle
|
Explanation:
Detailed explanation-1: -Most of the solute reabsorbed in the proximal tubule is in the form of sodium bicarbonate and sodium chloride, and about 70% of the sodium reabsorption occurs here.
Detailed explanation-2: -Structure of the Nephron The nephron is the unit of the kidney responsible for ultrafiltration of the blood and reabsorption or excretion of products in the subsequent filtrate.
Detailed explanation-3: -Proximal tubules are responsible for reabsorbing approximately 65% of filtered load and most, if not all, of filtered amino acids, glucose, solutes, and low molecular weight proteins. Proximal tubules also play a key role in regulating acid-base balance by reabsorbing approximately 80% of filtered bicarbonate.
