The Immune System Fights for You PowerPoint has 38 slides to tell the story of how the immune system protects your body from pathogens. In this slide show, the pathogens or the bad guys are introduced. Then, the immune system's first and second line of defense enter the picture and the process by which they fight these pathogens are explained. Next, the powerpoint focuses specifically on viruses and bacterias, providing details about the structure, method of transmission, and diseases caused by these two pathogens. Lastly, the slideshow concludes with vaccinations and antibiotics. I hope this visually appealing slide show story will captivate your students' attention and interest in learning about the immune system.
