FREE animated function of the appendix

When in comes to explaining the role of the human vermiform appendix, I must dispel students' belief that it has no role. And then I must try to convey that it has an immune function while at the same time promoting microbial growth.

Being a visual learner by preference, and therefore preferentially a visual teacher, I find any concept easier to teach if I can draw a picture of it.  Even better if I can put that picture into motion.

I recently uploaded a new set of animated PowerPoint slides that anyone can use to explain the immune function of the appendix.

To download and view the FREE set of slides, go to http://www.mediafire.com/file/jqgizrv1xr8s6kd/AppendixFunction-LionDen-KPatton.pptx

To access the file, you'll need a password.  If you don't already have a current password to the Lion Den Slide Collection, you can get one by filling out the form at http://my-ap.us/eOtyVq

Feel free to use it in your classroom or website (or both).

I'll be adding a narrated version to my YouTube channel soon at youtube.com/user/kevintpatton

Video: Neutrophils to the Rescue

Have you seen this video from Science Videolab that shows fluorescent-stained neutrophils rushing toward the site of a tissue injury?

The clip actually strings together several videos showing bright green neutrophils rushing toward damaged cells in liver tissue (seen as bright red areas).  The narrator explains in simple terms what is going on and what it means in understanding what happens when tissue damage occurs.

This is a great FREE video to show your class when discussing any or all of these topics:

• WBCs in general
• Neutrophils
• Immune response
• Inflammation
• Chemotaxis

Check out the video!
