Assertion `:-` Proximal convoluted tubule is lined by brush-bordered cuboidal epithelium.
Reason `:-` PCT is main site of selective reabsorption of useful material from nephric filtrate.

These questions consist of two statements each,printed as Assertion and Reason.While answering these questions you are required to chose any one of the following four responses. If both Assertion and Reason are true and Reason in correct explanation of Assertion. If both assertion and Reason are true but reason is not correct explanation of Assertion. If Assertion is true but Reason is false. If both Assertion and Reason are false. Assertion:Proximal convoluted tubule is lined by brush-bordered cuboidal epitheliium. Reason:PCT is main site of selective reabsorption of useful materials from nephric filtrate.

Read the following statements (a)in tubular reabsorption, substances like glucose, amino acid,Na^+, nitrogenous waste etc are reabsorbed by active transport, while reabsorption of water occur by passive transport (b) 50 -60% of electrolytes and water are absorbed by brush bordered cuboidal epithelium of PCT(c) conditional reabsorption of Na^+ and selective secretion of H^+ and K^+ occurs in DCT(d) filtrate gets concentrated as it moves upward in ascending limb of loop of henle. find the correct option regarding true or false statement.

Which of theses statements about proximal convoluted tubule is/are true? I. it is lined by simple columnar brush border epithelium which increases the surface area for reabsorption. II Nearly all of the essential nutrients and 70%-80% of electrolytes and water are reabsorbed by this segment. III. It selectively secretes hydrogen ions, ammonia and potassium ions into the filtrate. IV. It is the most convoluted part of the nephron and is present in the medullary region of the kidney.

Proximal convoluted tubule (PCT) is lined with (a) cuboidal epithelium (b) simple brush -border epithelium (c) columnar epithelium (d) simple cuboidal brush border epithelium

Assertion :- Simple cuboidal brush bordered epthelium is found in PCT of nephrons Reason :- Maximum reabsorption of substances takses place in PCT of nepthrons.
