The proximal convoluted tubule is
WebbThe function of the proximal tubule is essentially reabsorption of filtrate in accordance with the needs of homeostasis (equilibrium), whereas the distal part of the nephron and collecting duct are mainly concerned with the detailed regulation of water, electrolyte, and hydrogen-ion balance. Webbproximal tubule by an insulin-independent process. The ability of the proximal tubule to reabsorb glucose amplifies as the filtered load is increased by either an elevation in plasma glucose or an increase in glomerular filtration rate. This enhancement eventually reaches a threshold (T m glucose) that represents the maximal reab-
