Solution & Step-by-step Explanation

- PCT: Reabsorbs most nutrients ( - of electrolytes and water).Descending limb: Permeable to water but almost impermeable to electrolytes (water reabsorption).Ascending limb: Impermeable to water but allows transport of electrolytes (salt reabsorption).DCT: Site for conditional reabsorption of and water (influenced by aldosterone/).
