Props!!! These are great videos. Confession: I put you on double time for all you lectures and I really like that you use the white board to both draw and write the concepts you talk about. I mean, obviously, if I'm on KZitem watching lectures, then I'm a visual learner by nature and most likely have a shorter than average attention span. On double time, your lectures are a little over 20 min soit perfect for me. I don't find myself getting distracted waiting for you get to your next point (or to finish drawing 25 water molecules 😁 ) So thanks for providing content for learners like me and keep up the great work. These videos are a fantastic way to refresh and review these essential building block topics of Anatomy and Physiology.

I have a question: If the watermolecules exert a force downwards (or to the edge of the alveoli, towards the outside), then why does it cause the alveoli to collapse? To me, it would make a lot more sense that the alveoli would collapse if there was a force towards the inside of the alveoli instead of the outside... Please excuse the forming of this question, English is not my first language :o

I don't know about that "downward force " thing(I myself didn't get that actually) but just to make an understanding I've seen it as since the air liquid interface molecules are experiencing force due to surface tension they tend to decrease the number of surface molecules and hence tend to reduce the surface area which makes the alveoli collapse towards the centre....hope this makes some sense...

When you have a downward force of the water-molecules, you have an increased surface tension. This leads to an increased collapsing pressure.

It's because of the air and water interaction..since the water is causing the surface tension of the alveoli to increase by going deeper..the alveoli collapses so that the air leaves and the tension decreases and the alveoli is not under tension..hope you got it

@Cocolhasa In short, there is a force exerted towards the centre of the alveolus by the water due to its desire to maintain a low surface area. The water covering the inner lining of the alveolus tries to assume the least surface area possible by cohering with one another. This is due to the fact that water is a polar molecule and can form hydrogen bonds with each other, and the ideal scenario for the water is to get into its lowest energy state. When you inhale, you are pumping more air into the alveoli. To get the alveolus to expand, the water that is stuck to the lining of the alveolus also has to expand with it. This increases the surface area of the water, and the water doesn't want that. The water produces a force that exerts towards the centre of the alveolus, sort of like a water droplet trying to maintain its structure to achieve its lowest energy state. That is surface tension.

@sarahgloria1402
5 жыл бұрын
Juan B. Cisneros this is what i think it is : when air goes in the alveoli it interacts with that h20 molecules and because the water molecules don t want to interact (causes tension between them) they ' run away' like some kids run to their mom that is the wall of the alveoli .The alveoli thinks oh i know what s the problem we need to make that air go away so it doesnt create tension with my kids so it collapses and get s that air out.
@juanbacisneros
5 жыл бұрын
Sarah Gloria I’ve been thinking about it... my guess is that it collapses when the air goes out of the alveoli. Because since air is not anymore in the alveolar space, then the water molecules can approach. Since they’re more close to each other, they form hydrogen bridges and then the alveoli collapses (because water is together). Here, surfactant would impede water molecules to get together when they’re are close at inspiration. Do you think that makes sense?
@sarahgloria1402
5 жыл бұрын
Juan B. Cisneros Your answer made me see what s wrong in what i said.When air enters the alveoli the surfactant helps us conserve energy since there are those strong hydrogen interactions makes them easier and let s the alveoli to expand.Secondly the the layer of water gets thinner and the tension created will push the alveoli which because of it s elasticity and because the air going out (because of it s gradient) would collapse if there wasn t surfactant that it this case will prevent those hydrogen interactions to be so strong and the alveoli collapses without collpsing( the walls won t stick to one another).i think this is what you said.
@juanbacisneros
5 жыл бұрын
Sarah Gloria So could we conclude in that there are two reasons, right? The first being the fact that if the air leaves the alveoli, the water molecules will approach. The second, that the recoil generated by the first expansion, will make the alveoli colapse. In the second reason we could apply Laplace; P=(2xT)/r In some way, the recoiling works like in the heart, which is mainly explained by the Frank-Starling relationship.
