Explain and give examples of the four major functions of the nephron. Be specific about what part of the nephron performs each function. (19)
Filtration occurs in Bowman's capsule where blood turns into filtrate
Reabsorption occurs in the proximal tubule, Loop of Henle, distal tubule, and collecting duct. when substances of filtrate move from the lumen to the peritubular capillaries, like H2O being reabsorb in the Loop of Henle.
Secretion occurs in PCT, DCT, and CD. Removal of molecules from the blood to the lumen, like organic anions from blood to lumen in the PCT
Excretion is the removal of urine from the CD to the bladder.
