Question

Quizplus · Accepted Answer

Tubular reabsorption involves the selective transport of nutrients and salts from the filtrate in the renal tubules back to the bloodstream. This helps to maintain the balance of electrolytes and nutrients in the body. Plasma proteins are too large to be filtered and therefore are not present in the filtrate. Excess hydrogen ions are removed from the blood during tubular secretion, not reabsorption. Excess water can be reabsorbed or excreted depending on the body's hydration status. Drugs and foreign substances may be reabsorbed or secreted depending on their size and charge.
