062 Pressure Changes during Breathing

[@InteractiveBiology]

@yavneh911 Glad to know that. :) Leslie is indeed a great teacher! You can keep on learning more Biology stuff from our website. There will be more videos that will be uploaded so, please stay tuned!

[@InteractiveBiology]

@youhaventgotaprayer You're very much welcome. Do stay tuned for more as Leslie plans to put up more Biology videos coming very soon.

[@rocker4life1234]

One more thing to note: The External Intercostal muscles and the Accessory Muscles ("neck muscles") are only used during exercise and/or forced breathing. With expiration, muscles are only used during forced breathing, as the tendency expire is brought on by the abdominal pressure built while respiring. So if you're breathing normally, no muscles should be used while expiring.

[@heresheis3466]

just a minor clarification, though I LOVE your videos, keep up the good work! During expiration, the pleural cavity pressure is still LESS than the pressure in the lungs (intrapulmonary pressure). During inspiration, it is the relative pressure of pleural to pulmonary that causes the influx of air as well as the relative difference of intrapulmonary to atmospheric (greater, at least -1mmHg), pulling air into the lungs. Air flows down gradient until Ppul = Patm. The pressure always wants to be =

[@masterchriswong]

Very useful, thank you. Despite understanding Boyle's law, I was having a hard time orienting myself on the movement of the diaphragm, intercostals, and lungs. Awesome job.

[@InteractiveBiology]

@jckpink7 You're welcome! We're glad to know you're finding value in them. Stay tuned! We have new Biology videos coming soon!

[@butabobotabu]

Also, could you please go into a little more details about how the decreasing pressure in the pleural cavity can affect the pressure inside the pulmonary cavity? Thanks a lot.

[@InteractiveBiology]

@kiddlatoya Thanks, I look forward to making MANY more :)

[@butabobotabu]

Your videos are really helpful. I always look for any videos that is related to the topic I work on before I start reading my lab manual.

[@4leafclover987]

Excellent demonstration! I wish you included alveolar pressures too, though.

[@muhammadnurariff4833]

you're saving my sem exams. I LOVE YOU

[@malipal333]

This was really useful and helpful. I wish you had a video of ventilation-perfusion coupling. I have never watched a video from you that I don't understand, and ventilation-perfusion coupling is hard.

[@elenamaraki1090]

keep uploading biology videos !!! you have made my university studyings a lot easier !!!! Good Job

[@11rob09a]

Great videos! always help me understand these things when im confused by uni!

[@InteractiveBiology]

@michaelc5876 Please refer to our website at Interactive Biology for a list of complete videos. Thank you so much! :)

[@mohammedbanenany3045]

best video that i seen about thoracic pressure!!

[@InteractiveBiology]

Thanks 😉

[@InteractiveBiology]

@oneaware Glad to know it's helping. All the best!

[@karengrima7995]

Your videos make my life much simpler....THANK YOU!!!!

[@Qydyorijbdj]

Karen Grima same for me

[@Mr.ZEZExSAURUS]

hello, I have one doubt. Why the contraction of the diaphragm and ultimately the increase of the size of the thoracic cavity reduces the pressure of the pleural cavity?

[@rahularvind5078]

Ezequiel Meriggi Boyle's Law, pressure of a gas is inversely proportional to its volume.

[@desireefields8017]

Does breathing affect sound on the tympanic membrane causing a change in vibration of the cillary muscles in the ear?

[@JJO-oc4le]

The intercostal muscles don't move the thorax up in the process of inspiration. It stabilizes the ribs and also strengthens the thorax.

[@brentlina6450]

Thank you! You just saved me from my Anaphy Report!!

[@michelledavin406]

Enjoying expanding my knowledge and learning more and more Thank you !

[@ebtihalalmajdoub]

This help me alot thanx really

[@NBAfan1993]

Don't the lungs collapse during inspiration? :S

[@محمدفاضلمحمد-ج1ك]

thanks

[@sheenamae09]

my finals is two days from now!!! Argh nursing !!!! LOL

[@nolikeygsomnipresence270]

Fucking tell me what pressure there is inside the thoracic cavity during inspiration. 50 mmgh? 3? 100? Just say it!

[@yanghyunseuktoanyone8399]

Thank uu

[@bomhayhay]

thank U a lot

[@Martin-uj4mi]

Can I hire you at my school? Hello? :)

[@poochyboi]

muchos gracias. when i don't know wtf textbooks are trying to say. i come to you.

[@DestinedFX]

Good thing I skimmed through the vid to see if I was going to waste my time, because he didn’t really explain the pressures much

[@soneelita]

BOOKS AND TEACHERS NEVA MADE SENSE TO ME BUT DIS VIDEO DOES ...

[@monicamikael3145]

i love you so much thank you

[@firdos4857]

👍

[@dro4189]

❤❤❤

[@dro4189]

💔💔💔

[@shjmm192]

pov: you watch this in 2021

[@InteractiveBiology]

And hopefully it’s still relevant 😃

[@obaid2878]

I need your brain

[@Roy-dh9nt]

It's 'air' not 'ear'. You always pronounce like 'ear'

[@celaenas3016]

do you actually have any biology experience or did they just look for an asian person within a 10m radius and find you???

[@MChell87]

he sound Bajan

[@ruifgmonteiro]

Excellent!

[@selenakitanovic447]

Thank you
