Excretory Products and their Elimination NEET PYQs

Given below are statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Nephrons are of two types: Cortical & Juxta medullary, based on their relative position in cortex and medulla.
Reason R: Juxta medullary nephrons have short loop of Henle whereas, cortical nephrons have longer loop of Henle.
In the light of the above statements, choose the correct answer from the options given below:

Which of the following statements are correct?
A.An excessive loss of body fluid from the body switches off osmoreceptors.
B.ADH facilitates water reabsorption to prevent diuresis.
C.ANF causes vasodilation.
D.ADH causes increase in blood pressure.
E.ADH is responsible for decrease in GFR.
Choose the correct answer from the options given below:

Nitrogenous waste is excreted in the form of pellet or paste by:

The increase in osmolarity from outer to inner medullary interstitium is maintained due to:
I. Close proximity between Henle's loop and vasa recta
II. Counter current mechanism
III. Selective secretion of HCO₃^- and hydrogen ions in PCT
IV. Higher blood pressure in glomerular capillaries

Select the correct statement:

Presence of which of the following conditions in urine are indicative of Diabetes Mellitus?

Which of the following would help in prevention of diuresis?

Which of the following factors is responsible for the formation of concentrated urine?

Use of an artificial kidney during hemodialysis may result in:
(A) Nitrogenous waste build-up in the body
(B) Non-elimination of excess potassium ions
(C) Reduced absorption of calcium ions from gastrointestinal tract
(D) Reduced RBC production
Which of the following options is the most appropiate?

Given below are two statements:

Statements I: In the nephron the descending limb of loop of Henle is impermeable to water and permeable to electrolytes.

Statement II: The proximal convoluted tubule is lined by simple columnar brush border epithelium and increases the surface area for reabsorption.

In the light of the above statements, choose the correct answer fropm the options given below:
