Question 89

Needed water and dissolved materials are present in nephron fluid. What does selective reabsorption do with them?

  1. Sends all useful substances out of the body
  2. Moves them from blood into the nephron
  3. Prevents any water returning to blood
  4. Returns them from nephron fluid to bloodBonne réponse

Explication

Selective reabsorption recovers useful water and solutes from the nephron and returns them to the surrounding blood. Movement in the opposite direction fails the stated recovery purpose because it would add material to nephron fluid instead.
