Vasa recta in cortical nephrons :

1. Arises from afferent arteriole rather than efferent arteriole

2. Does not get involved in counter current exchange with loop of Henle

3. Carries deoxygenated blood rich in urea

4. Is absent or highly reduced 

The network of peritubular capillaries is formed by

1. Efferent Arteriole

2. Afferent Arteriole

3. Efferent Arteries

4. Afferent Arteries

The concentrations of which plasma electrolyte is not regulated mainly by the kidneys?

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.
