IGCSE Biology - Blood Vessels, Circulation and the Heart Presentation
This is an animated PowerPoint presentation that covers the Blood Vessels, Circulation and the Heart part of Section 2.3 Blood and Circulation of the Edexcel IGCSE Biology course.
The PowerPoint covers the following questions:
Can you explain why simple, unicellular organisms rely on diffusion for movement of substances into and out of the cell? Why do multicellular organisms need a transport system? What are the differences in structure between arteries, veins and capillaries? What are the roles of arteries, veins and capillaries? Can you recall the general plan of the human circulatory system including blood vessels to and from the heart, the lungs, the liver and the kidneys? Can you label a diagram of the human heart and explain how it functions? How does heart rate change during exercise and under the influence of adrenaline?
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.
