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