Kidneys & Osmoregulation Lesson Pack GCSE

A clear, ready-to-teach lesson pack covering the structure and function of the kidneys and the role of the nephron in maintaining homeostasis. This resource takes students from kidney anatomy through to ultrafiltration, osmoregulation and treatments for kidney failure, building understanding step-by-step.

The pack contains three fully editable PowerPoint lessons designed for GCSE Biology. Each lesson includes retrieval questions, key vocabulary, explanations of core processes and knowledge-check activities to support understanding of this challenging topic.

Lessons progress from organ structure → microscopic processes → medical applications, helping students connect biological concepts with real-world treatments such as dialysis and kidney transplants.
