I love to find videos or apps that help review or overview essential concepts.

This is slightly longer, just under 7 minutes, but it's a more complete overview of the immune system. It still isn't perfect, but it's hard to get a good, complete, perfectly accurate overview of an entire system in such a short video. This is one of the best I've seen. I haven't watch the other videos, but I'll be checking them out - watch for updates on the channel here. Why You Are Still Alive - The Immune System Explained
