The morphology of the proximal tubule cells was covered briefly in Chap. 2, but will be considered in more detail here. The proximal tubule is divisible into the convoluted portion, or pars convoluta, which begins immediately behind the glomerulus, and the straight portion, or pars recta, which passes into the medulla to become the loop of Henle. The cells of these two portions have somewhat different structures (Fig. 2.4) and there are cells of an intermediate type linking the two portions. The transport functions of the proximal tubule are primarily dependent on the pars convoluta cells.
