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

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.
