Roofs is the best professor! I was nervous about taking this course as it’s not easy material, but he makes it easy and fun! He goes above and beyond for his students, he’ll explain something as much as you want and makes sure you’re comfortable with the info. He made us online quizzes and videos to help us understand. Awesome educator AND person!

This was the most thorough and helpful of all the videos that I watched here on Youtube.  He went into WHY not simply  the quick and dirty.  This is lasting knowledge.  Also the link to the practice problems were money!

You are honestly such a great teacher!! I’m a nursing student and your videos have really helped 🙂 thank you!
– Sarah on Compensation of Respiratory and Metabolic Acidosis and Alkalosis

I don’t know what it is but it’s easy to follow what you’re saying. Maybe your voice isn’t grating or boring. You have a good way of explaining things which makes it easier to listen to and understand. Excellent.

– NaturallyJW on External and Internal Respiration (Gas Exchange) SIMPLIFIED!!!

OK — you just saved my life…. I had read the text on this process 5 times and was so confused and frustrated that my heart rate was going up….(LOL). However, after watching your 3-part tutorial, I COMPLETELY GET IT……… THANK-YOU so much… Your descriptions are simple, and I love the tips on how to remember things and also how to deduce the answers on the “test” that you showed. Can’t say enough….. you took me from “ready-for-tears” to “ready-for-cheers.”
