CAIE IGCSE Biology EXTENDED 13.1.5 Structure & function of a nephron
Practise using nephron diagrams, filtrate composition and concentration data to trace filtration, selective reabsorption and urine formation.
How this is tested
- label glomerulus, tubule and blood vessels on nephron diagrams and state their roles
- compare blood, filtrate and urine to decide which substances are filtered or reabsorbed
- calculate percentage reabsorption from concentration tables for ions or other solutes
