The concentrations of which plasma electrolyte is not regulated mainly by the kidneys?
1. hydrogen
2. potassium

Which of the parts labeled A–D are correctly identified with their functions?
(1) A–Afferent arteriole – Carries the blood away from the glomerulus towards the renal vein
(2) B–Brush border – Create minute spaces epithelium for the filtration of blood into the Bowman’s capsule
(3) C–Henle’s loop – Maximum reabsorption of major substances from glomerular filtrate
(4) D–DCT – Secretion of K+ ions into the filtrate
In the accompanying diagram of a human nephron the functional parts are labelled as A, B, C, D, E.
Study the diagram to answer the questions given
P: | Active secretion of H+ and K+ into the filtrate occurs in which parts? |
Q: | Conditional reabsorption of Na+ and water is a function of |
R: | Reabsorption of water is minimum in which segment? |
Choose the correct option:
P | Q | R | |
1. | B,D | C | E |
2. | A,B,C | C | E |
3. | D,E | D | C |
4. | A,D,E | E | C |
