Year 13 BTEC students get upclose with real life kidneys

This week, our Year 13 BTEC students have been learning about the gross anatomy of the kidney; identifying the renal cortex, medulla, pelvis and renal calyces, by dissecting kidneys.

The students put hydrogen peroxide onto the kidney. An enzyme in the cells of the kidney called catalase breaks the hydrogen peroxide down into water and oxygen gas, which gets trapped in the tubules of the nephron (the part that filters the blood and produces urine). This makes them visible as the trapped gas makes them look white.
