It s amazing that I went to school for Sports and Medicine because I was curious of how my body function . Un fortunately, I found things hard to grasp and therefore, lost interest. I however, came into these videos and everything seems so simple and exciting to understand. Thank you so much Dr. Campbell for your extraordinary explanation. I wish that you was my teacher while I was in school.

Beautiful presentation and explanation. 78 years old spouse is recommended to undergo pulmonary test which as lay man can’t understand. Fortunately, I got access to your channel, watched the respiratory system and endeavoured to understand about recommended test and is beautifully understood what the procedure can be.
