My professor spent 15 minutes on this topic and I still didn't get it. I watched the first 67 seconds of this video and it started making sense already.

[@sapphirestone8672]

Think about it this way. When you air up your tire you have your tires pressure let’s say 20 psi. Your air tank would need to be higher pressure than your tire to air it up but let’s say this air tank is only pressurized to 26psi and it’s not plugged in. When you go to air up your tire the pressure in the tank and in the tire will even out at 23 psi. Or like a soda can is pressurized the pressure in the soda is higher that the atmospheric pressure so when you open it it makes a sound which is the air escaping. the pressure inside the can and the atmosphere is equal. It’s the same principle just apply it to the individual gas pressures.

When the alveolar pressure of oxygen makes the blood partial pressure from 40 to 104 (is the alveolar partial pressure of oxygen decreased or remains 104 despite transferring some oxygen to the blood?)

A few mistakes... in Tidal Ventilation it is not 500ml that reach the lungs due to dead space. More like 350ml. And the capillaries cover the majority of alveoli surface, rather than being isolated dots

This was an amazing video, thank you so much! I have a question. Is it possible for proteins to pass through into the capillaries from the alveoli? Thanks again!

[@buggamingff6818]

I too have same question

[@kaymonroe4386]

@@buggamingff6818 I know I am very late to this but hey ho, only an A-Level Student here but I'm 95% sure that most proteins, erythrocytes, and leucocytes are too large to pass through the fenestration of the capillaries. Some small proteins may be able to pass through, however.

[@m.prasadprasad9080]

Good explanation

[@msldt9675]

Thank you so much. You explained it well. 😘

[@ivanvj]

What it is mention at 1:45 about differences in volume between alveoli and pulmonary capillaries as the reason for gas interchange is wrong, it occurs because of their diffrent solubility into blood which is determined by their Henry constants values, as well as their partial pressures in the inhaled "fresh" air. Alveolar air composition is what it is left after gas exchange. O2 exchange is almost the same that CO2 but in opposite directions, and like in a combustion process H2O is also produced and expelled as water vapor which goes into our humid breath.

[@Wayoflife-o2k]

How does the oxygen partial pressure of oxygen change from 40 to 104 and is it that after the change it becomes stable so their is no net movement of oxygen molecules

[@husseinal-dulaimimbchb9052]

[@BryanGomez-g6o]

nonsense of course you dont understand

[@spurthichadharam9144]

Thank you for educating us, I think depending on air pressure movements of air in lungs between arteries and veins also may or can switch between them..Due to this for some processes like sexual intercourse and eating meat due to the high pressure reactions in wind pipes and blood vessels there is a chance for severe pain blocking of air passage and severe acidic reactions in brain, also for the process purity thoughts replace impure thoughts..so whatever we think see say and do seems pure and right first and then wrong, it s so difficult to digest so confusing to accept and live life at normal speed or manage time..

[@paulschult7161]

Great video but there is one thing I don't understand. Why exactly does the pO2 in the alveola remain constant at 100 mmHg even though oxygen diffuses into the blood. And why does the pO2 in the tissue remain constant at 40 mmHg even though oxygen diffuses there. Like why does it not increase ?

[@ayeshathefairy8333]

because we are constantly inhaling and exhaling.

Can’t burp? Have gurgling noises in chest/throat? You might have “r-cpd” a rare and painful condition that involves the upper sphincter. The muscle is too tight and causes the inability to burp Symptoms involve Gurgling noises, bloating, nausea, vomiting and pressure in chest.

What makes CO2's alveolar pressure 40mmHg?

[@UrChoiceTV]

Does only there occur exchange ko oxygen or there may be chance of nitrogen exchange

[@gprime204]

Thuglife Nepal The concentration of a gas in a liquid is directly proportional to the partial pressure AND solubility of that gas. This is Henry’s Law. Nitrogen is not very soluble in blood so it doesn’t diffuse into it very much.

[@fakihammadi6330]

nitrogen can't occur exchange bcz there is no metabolic activities in the body which consume nitrogen

[@snrnsjd]

Can someone Tell me how fast is this exchange happening? My guess is that it is very fast

[@codrut913]

[@Nah.inc.]

inhaled air unloads o2 and picks up co2 in alveoli while blood picks up o2 and unload co2? can someone make this make sense

[@onherownway]

there is hemoglobin.ıf there is O2 too much in alveoli -------------->Hb +O2 ---------------->HbO2(CO2 left from alveoli) ıf there is CO2 too much in tissue capillary -------------->Hb +O2 ---------------->HbCO2(OO2 left from tissue cappilary) i hope ı make sense inside you

[@yellowcactuslovesu]

This is called diffusion. It happens during respiration. Carbon dioxide from the blood vessels (high CO2 concentration) is exchanged with oxygen. In the alveoli (high concentration of oxygen), oxygen is exchanged with carbon dioxide from the blood vessels

[@megbristy2147]

😊😊

[@muhrohaanmasood4961]
