Function
V Filtration of blood to make filtrate.
Mainly selective tubular reabsorption of glucose, amino acids, Na then CI, H,0 follows by
v osmosis. Reabsorption of bicarbonate.
Also tubular secretion of NH, and H; tubular secretion of drugs (e.g. penicillin).
v To create and maintain the concentration gradient across the medulla.
v Impermeable to NaCl, permeable to H,0. Water leaves filtrate (in response to concentration of
surrounding interstitial fluid) as it descends making the filtrate more concentrated.
