Excretory Products and Their Elimination PYQs

Arrange the following events occurring in Renin-Angiotensin mechanism in the correct order: A. Increase in blood pressure and glomerular filtration rate B. Reabsorption of Na⁺ and water from distal parts of tubule due to Aldosterone C. Fall in glomerular filtration rate D. Vasoconstriction by Angiotensin II and release of Aldosterone E. Renin converts Angiotensinogen into Angiotensin I, followed by Angiotensin II Choose the correct answer from the options given below:

The JGA (Juxta Glomerular Apparatus) is a special sensitive region formed by cellular modifications in ______ related to the same nephron.

Which of the following diagrams is correct with regard to the proximal (P) and distal (D) tubule ?

Given below are two statements : Statement 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 cuboidal brush border epithelium and increases the surface area for reabsorption. In the light of the above statements, choose the correct answer from the options given below :

Choose the correct statement given below regarding juxta medullary nephron.

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 and 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.
