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.
