- You may use the video as a revision for the topic or as a self-assessment tool. For the purpose of self-assessment, pause the video at the beginning of each slide and take your time in reading the question and coming up with the answer then replay the video to confirm your answer and listen to further comments and explanations.
00:00 Intro
00:26 Q1 Epithelium identification
03:10 Q2 Layers of a respiratory passage and function
05:14 Q3 Layers of respiratory passages
07:24 Q4 Identifying a respiratory passage and giving reasons
09:25 Q5 Identifying a respiratory passage and differentiating between the conducting passages
11:24 Q6 Cellular structures in the mucosa
13:36 Q7 Alveolar cells
15:25 Q8 Alveolar formation
17:24 Q9 Dust cells
After completing this video you will be able to:
Differentiate between
Trachea, bronchus and bronchiole
Type I and Type II alveolar cells
Alveolar duct and alveolar sac
Explain the role of the following respiratory passages structures:
Mucous, cilia, cartilage, smooth muscle, Clara cell, type I & II alveolar cells, alveolar macrophages, goblet cells, neuroendocrine cells, basal cells,
Identify: respiratory epithelium, basement membrane, cilia, goblet cell, basal cell, fibroblast, lymphocyte, dust cell

Every practical you get me through the histology section. Thank you!
The Greatest video ever, you've covered our material for the exam. Thank you.
This was extremely helpful. Your explanations are so clear. Thank you!!!!
This is mind blowing. I went from knowing absolutely nothing to having a better understanding of this.
What an excellent video.
Glad it was helpful!
Your videos are very high yield information Doctor. In fact, seems like you tell everything what my Professor wants to hear. Thank you and keep it up.
This was so helpful and well explained, thank you very much!!
Thank you so much! Your presentation is clear, correct, and very interesting. I appreciate this tutorial. I have finals next week and this review is just what I need.
Wow you explained nearly everything for respiratory histo! great job.. no amazing Job. Everything explained in one fell swoop.
your explanation is insane keep it up prof
the best video about this subject so far because not only practical but also you gave theoritical informations, helped me a lot. respect and Salam from Turkey to you sir
Wow, thanks!
8:05 I was just taught that the layers were. Mucosa, fibromusculocartilaginous layer then adventitia.
9:09 this gap in the cartilage also allows for easy passage of the bolus (ball of food) down the esophagus on its way to the stomach.
10:28 something I knowticed while studing the respiratory system was that the further you get into the bronchus the LESS gobles cells and hyaline cartilage you see but for exchange see MORE smooth m. and elastic fibers.
14:27 Type 2 phneumocytes are NOT as frequent as the 1 phneumocytes!
17:50 Dust cells also called coniophages!
Great video! Thank you!
Thanks for the comments and for your interest in the channel.
Thank u so much sir. Your each n every video is so helpful. Really u r a great teacher
Thank you man serious respect
Excellent job sir ....thank you very much sir
Thank you. Very helpful!
You are really informative ...Well done
It's really helpfull sir.. expecting more from u.. :)
this is the only reason i understand respiratory histology - thank you !
You're welcome! :-)
AMAZING! Many Thanks! still relevant and helpful in Nov 2021
Glad it helped!
This was very helpful, thank you so much! I share it with all my friends :)
Thanks for sharing!!
Thank you very much
Thank you!
im confused regarding the histology slide showing the terminal bronchiole , i thought that would rather be a respiratory bronchiole
underrated channel
you're freaking amazing. Please do multiple histology videos!
Glad it is helpful. Search withing the channel for many other similar histology files.
Awesome work!! Very helpful
+ruby oswere thank you for the feedback

Thank u so much
Thank you too
Perfeccccccct
Thaaaanks!
Just saved me oh 🤝✨
Thank you
You're welcome
Sir, if the smooth muscle of bronchus has a spiral course, it can not be a continuous circumferential layer in a cross section. Am I correct sir?
I did not understand your question. Could you please provide more details? Why should the smooth muscle fibers have a spiral course?
@@akram.jaffar Sir, Thank you for your response. Sir, you told that the smooth muscle in bronchus has a spiral course. Sir, I am asking can we see a continuous circumferential muscle layer in a cross section of the bronchus,if muscle layer has a spiral course along the wall?
Yes, the can still be as a complete layer because although they are spiral in orientation in some place but they are present all around the circumference.This spiral arrangement permits contraction of the bronchi in both length and diameter during expiration. Good question.
@@akram.jaffar Sir, I understood. Your answer is very clear. Thank you very much.
This is perfect
+abdulhamid usman thank you

ليش ال terminal bronchiole گلنا simple cuboidal مو هي simple columnar ؟ 🥲
Because the thickness of the epithelium gets thinner and thinner as we go distally. So from columnar to cuboidal to squamous when reaching the respiratory portion of the passages for example in the alveoli. The thin epithelium serves to facilitate exchange.
Thanks , l think your Iraqi
Yes!
