AQA GCSE Biology: The kidney – ultrafiltration, osmoregulation & excretion – kidney dialysis & trans

This is an annotated and narrated powerpoint presentation for GCSE Biology and Trilogy to help next year’s Year 11 students catch up after Covid19. It details how the kidney filters the blood to remove urea and selectively reabsorb glucose, amino acids and water, how the permeability of the kidney tubules id increased by ADH and uses this as an example of negative feedback and how amino acids are deaminated. It finishes, looking at how kidney failure can be treated by kidney dialysis or transplants. It has 13 multiple choice questions and a RAG sheet for students to test their knowledge and understanding.
