2.72 Water re-absorption

1. We have blood coming into the kidney. It is placed under high pressure.
2. The dissolved contents in the blood are forced into the bowman's capule's tube, and would become known as the glomerula filtrate.
3. This glomerula filtrate contained salts, water, glucose and urea.
4. When the filtration occurs, it filters out too much water.
5. The filtrate passes along the tube and once it reaches the collecting duct, water is removed from the filtrate.
6. that water is returned back to blood vessels therefore the water has been selected and has been reabsorped into the blood. We get the word, selective reabsorption.
7. Selective reabsorption takes place in the collecting duct.
