Which of the following diagrams is correct with regard to the proximal (P) and distal (D) tubule of the nephron?
Correct answer: D — D
In nephron structure, the proximal convoluted tubule (P) is located near the Bowman's capsule and has brush border epithelium for maximum reabsorption. The distal convoluted tubule (D) is positioned after the loop of Henle and connects to the collecting duct. The correct anatomical arrangement follows the path of filtrate flow through the nephron.
The renal tubule begins with a double walled cup-like structure called Bowman's capsule, which encloses the glomerulus. Glomerulus alongwith Bowman's capsule, is called the malpighian body or renal corpuscle. The tubule continues further to form a highly coiled network – proximal convoluted tubule
NTA tests whether students understand the sequence and nomenclature of nephron structures, particularly that Bowman's capsule + glomerulus together form the renal corpuscle (malpighian body), and the tubule continues as the proximal convoluted tubule (PCT). Students commonly confuse Bowman's capsule with the glomerulus itself, or mix up the names malpighian body and renal corpuscle. Remember: the glomerulus is the capillary network inside, Bowman's capsule is the cup-shaped structure around it, and together they're called either the renal corpuscle or malpighian body. The PCT follows immediately after, forming the beginning of the tubular component of the nephron.
