Net transport of key solutes (A–G) and fluid (H) along individual nephron segments in male and female rats. Colored bars denote superficial nephron values; white bars denote juxtamedullary values, computed as weighed totals of the five representative model juxtamedullary nephrons. Transport is taken to be positive out of a nephron segment. Insets: reproductions of distal segment values. PT, proximal tubule; DL, descending limb; LAL, thin ascending limb; TAL, thick ascending limb; DCT, distal convoluted tubule; CNT, connecting tubule; CD, collecting duct; TA, titratable acid.
