Question

Differentiate between the Following:

PCT and DCT

Answer 1

Basis of Difference	Proximal convoluted tubule (PCT)	Distal convoluted tubule (DCT)
Position	The PCT lies close to the glomerulus in the cortical region.	The DCT is the last part of the nephron and lies in the cortex after the loop of Henle.
Connection	It begins from the urinary end of Bowman's capsule.	It continues from the ascending limb of the loop of Henle.
Main function	It is the major site of selective reabsorption of water, glucose, amino acids and salts.	It carries out further reabsorption and tubular secretion of substances such as hydrogen and potassium ions.
Further connection	The PCT continues into the loop of Henle.	The DCT opens into a collecting duct, which carries urine towards the renal pelvis.
