Quizplus · Accepted Answer

The majority of tubular reabsorption takes place in the proximal tubules, where about 65% of the filtered sodium and water is reabsorbed, as well as other important substances like glucose and amino acids. The loop of Henle is primarily involved in creating a concentration gradient in the medulla, while the distal tubules and collecting ducts regulate electrolyte balance and water reabsorption based on hormonal signals. The glomerulus is not involved in tubular reabsorption, but rather in filtration at the beginning of the nephron.
