This is an animated PowerPoint presentation that covers the kidney part of Section 2.6 Homeostasis and Excretion of the Edexcel IGCSE Biology course.
The PowerPoint covers the following questions:
Can you define the term homeostasis? Do you know that the control of body temperature and water content are both examples of homeostasis? Can you name the organs of excretion, including the lungs, kidneys and skin? In what metabolic processes would you find oxygen and carbon dioxide as waste products? What does urine contain? How is the kidney involved in osmoregulation and excretion? Can you label a diagram of the urinary system? Can you label a diagram of a nephron? Can you explain the processes of ultrafiltration and selective reabsorption? Where in the nephron is water reabsorbed into the blood? How does ADH regulate the water content of the blood?
The PowerPoint is designed to directly address each relevant point in the syllabus. It is simple and straight to the point covering the topic in just the right amount of detail.
It is a fantastic resource for both teachers and students or a great tool for revision.
Many of the slides have animations in that will only work when viewed in slideshow mode, so please use that when working through the presentation.
