Which one of the following correctly explains the function of a specific part of the human nephron? (a) Podocytes : create minute spaces (slit pores) for the filtration of blood into the Bowman’s capsule (b) Henle’s loop : most reabsorption of the major substances from the glomerular filtrate (c) Distal convoluted tubule : reabsorption of K+ ions into the surrounding blood capillaries (d) Afferent arteriole : carries the blood away from the glomerulus towards renal vein.
