The world needs more teachers like you

Reading books are confusing without your helpful videos. You are a life saver!

I like to think of opsinization as "honey" that makes the target pathogen more delicious to phagocytes. Visual: bees to honey. "Bee"-cells respond, make honey, to attract "b"ears to eat them.

I haven't watched a single video of urz that didn't help me. You give lots of information without making it impossible for the simpletons to understand. Thanks a lot.

Listening to your explanations is the glue in my studying regimen. Thank you SO MUCH for these videos. I know I'm not only speaking for myself when I say that your videos are life savers.

Thank you! I’m studying to challenge the blood bank technologist boards on my own and it’s so hard teaching myself, but this helped so much!

[anastasiamccarter]

THANK YOU! I have an anatomy and physiology test tomorrow and no matter how many times I read the text I couldn't comprehend this information. This is helpful!

[mustapha]

It took my professor 3 lessons to explain this, you did a better job in 14 minutes !!!
