Selective Reabsorption

Question 1

What is selective re absorption?

Answer 1

useful products are reabsorbed from the glomerulus filtrate mostly by the proximal conducted tubule
and loop of hemle, distol conducted tubule, and collecting duct

Question 2

What happens during selective re absorption?

Answer 2

capillaries will wrap around nephron and useful substances are reabsorbed into the blood
poximal convulted tubule absorbs most of the molecules - has microvilli - increases SA for absorption
urine is filtrate with useful molecules removed
urine contains water, ions, urea, excess vitamins
