I love you so much Dr Campbell, you've been a blessing to me, you make science so simple and fun. You are a real educator. God bless you and your family. Long live Dr. Campbell
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.
You are a legend! You actually make the gas exchange process easy to understand! I couldn't understand it until watching this video! Thank you so much!
Hello, Doc. Just recently accidentally came across your well illustrated educational videos, and I am already a better high school biology teacher. You are my biology role model. Thank you so much.
Outstanding lecture!! We are learning about the respiratory system in my medical terminology class and these videos are a great supplement! It's really helping me understand the function of the respiratory system. Thank you so much for taking the time to post your lectures!
Thanks Dr. Campbell make Animal physiology much more simplest. After a long time I can understand circulatory system. I will never forget this lecture.
Yes I couldn’t agree more with the comments blessing this man, honestly, God bless Dr. John Campbell for making his channel with his soothing voice the easiest to understand on TH-cam, thank you, God bless you, your family and your TH-cam channel and please keep the videos coming to get me through med school! 👏💞🙏
Thank you Dr. Campbell for your well thought out youtube videos which have helped me enormously in my study of physiology. I am struggling to get a good understanding on the effects of gas exchange in high altitude environment and hope you could include this topic in your new videos. Thank you
This is a brilliant video that explains in layman's terms how co2 and O is exchanged from blood to air and vice versa. The Doc makes it simple to understand. When we know how our bodies work, hopefully we will respect and take care of them.
I am from Bangladesh i watch your videos which you lecture in cardio vascular system i just love that then i come here in respiratory system. Long live sir.
I really understand better when I see it visually and animated but I don't need all that because ur explanation and points u mention are elaborate enough. Thank you very much for your time and effort sir and may God bless you ❤️❤️❤️
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.
dr john campbell sir, the more i hear your treasured feedback, the more they attract me and give boost to my knowledge, i wish you a very happy and healthy new year. 10/01/2022
i was having such a hard time understanding this and you just made it so easy, thankyou so much. god bless you and your family. am completely hooked to your videos now
Dr john Campbell sir you are real master of your subject difficult points you clarify in such a simple way any one can understand thanks good wishes 12/05/2021
i heartly say you that very you hav very incredable knowledge of human body and that you explain in very simple way . i like your video . thank you....
I hope you're well sir ...🙏 I regret that my money is being wasted in institutions and teachers who can't explain the topics well as you explain i got the concepts in one day which they were trying to teach me from years . I'm very much grateful to you sir, May all your wishes come true 🙏❤️ Love the way you teach the topics in easiest way I also shared many of your vdeos of several topics to my friends so that they can also understand the topics well
Im just thinking out loud here: when there is more oxygen going in than out, and more carbon going out than in through the lungs, where do we make up that difference? Since, especially in adult life, we are in a quite stable state chemically. Is the extra oxygen converted to water and exits as sweat and urine? And the loss of carbon compensated through the intake of carbon rich foods? What other pathways are there? How would, theoretically, breatharians deal with this differnce in chemical exchange through the lungs, thinking as they don't take in carbon through food? And where does the extra hydrogen come from, in either breatharians or people with a food diet? Also, you come across as very patient in your teaching even though there are no "live" students, very impressice, great teaching!
Thanks Dr John Campbell ! I have a question Why respiratory system has muscles , while its contraction limits air flow to the lungs and in some conditions it can be life threatening ( Asthma ..)?
Extrinsic muscles are essential to alter the volumes of the thoracic cavity, this is how the pressures are altered to facilitate breathing in and out. While asthma is causes by bronchoconstriction of the bronchioles, it is mostly caused by inflammation. The bronchioles have smooth muscle in their walls. The reason there is smooth muscles in the walls of the bronchioles is so there can be constriction and dilation of the small airways. If they were fully dilated all of the time, infection would get into the alveoli more easily.

Fascinating, well explained. What about the Nitrogen?
You are born a helper
you explained this very well thank you!!
I wish I could always sit at your feet for lectures. You're a blessing.
Thank you!
You make Anatomy and Physiology simple
Thank you for wonderful explaination sir ❤️
Excellent...
Thanks a alot for the clear explanation 💚💚
Sir can you please make an elaborate video on Emphysema and the Elastic fibres in the alveoli
thank you so much!!!
Thanks Dr John Campbell !

I know this is anatomy and physiology , but I wish I had him as an instructor for when I took Pathophysiology.
