The renal tubule is the part of the nephron which contains tubular fluid that is filtered through the glomerulus. The renal tubule leads away from the Bowman's capsule and becomes highly coiled. The coiled portion is named the proximal convoluted tubule. Several of the distal convoluted tubules merge into the renal cortex to form a collecting duct, which in turn passes into the renal medulla, becoming larger and larger as it joins other collecting ducts; the resulting tube is called the ...
