Ultrafiltrate flows through the first part of the renal tubule, called the proximal convoluted tubule, which is a section of the renal tubule mainly located in the kidney's cortex that is responsible for the reabsorption of the majority of ultrafiltrate.The ultrafiltrate will then flow into the loop of Henle.he word 'proximal' in 'proximal convoluted tubule' implies it's near or attached to the renal corpuscle, and if you look at the image on your screen, you can also see how convoluted this duct is due to a bunch of twists and turns.
Kidney (corpuscles and tubules) In contrast, the secretory units of the kidney, called renal corpuscles, comprise a relatively small proportion of the kidney. The bulk of the kidney consists of highly specialized tubules, which correspond to the duct tree of a typical gland.he initial segment of the tubule is the proximal convoluted tubule. It is called proximal because it is nearest to the starting point (the renal corpuscle) and convoluted because it twists about (in contrast to the straight segments of tubule which form the loop of Henle).
