(b) : Nearly all of the essential nutrients and 70-80 per cent of electrolytes and water are reabsorbed by PCT. It is lined by simple cuboidal brush border epithelium, which increases the surface area for reabsorption. It is a coiled tubular segment, allowing more time and space for effective reabsorption.
