      Osmosis, If a person has chronic hypoxia, if the Carbohydrate intake is high, doesn’t the Glucose intake convert to Lactic acid exaberating the acidic pH?

    Brilliant! I'm a neonatal nurse trying to produce some teaching material on neonatal hypoxic ischaemic encephalopathy and how therapeutic hypothermia and xenon gas work. There's plenty of literature on this, but it's written for doctors, who have a better understanding of the background physiology than I have. I think I'm now getting the picture! Believe me, I'm deeply grateful.

    Hypoxia is a process which slowly becomes irreversible if not tacked in early stages ( like in the case of an MI ) and the end result is cell death . A good clinical pathological correlation would be with the 4 types of Hypoxia fundamentally explained. Thank you for posting . Great Job .

    The only down-side was that I spent the entire time waiting for the video to abruptly end midcourse, with its remainder pre-empted by a sales pitch to buy a membership.
    A lot of people are economically suffering right now. This would be a wonderful time for Osmosis to offer their videos free of charge, like Ninja Nerd, Khan Academy and Crash Course. (In my mind, Osmosis and Ninja Nerd are the best medical videos out there, by a wide margin.)
    (Also, in the past, comprehensiveness of your collection was a problem if you paid the monthly fee. The videos you had were great-- but there were too many gaps. That was a few years ago, so that might not still be an issue.)
    But the real issue is-- Great Job! A genuine public service. I hope you keep it up.

    @kiedranFan2035 Год назад

    Hello there. Id like to add that small charged molecules dont just diffuse into the cell.They need passive diffusion channels. This is needed because the cell needs such ions but at regulated levels. During hypoxia ATPases like the pumps fail more so then the ion channels do. So to stop all this from occuring you need to stop the ion channels from being expressed. Disrupt enough and the ion exhangers wont have the gradients needed either to work and the cell is free from bleeding out until apoptosis. In addition mitochondria could initiate apoptosis is their memebrane potential drops too, or mistakenly undergo mitophagy which is not what you want either. Lactate can be epelled from cells too by tranporter channels which is what cancer cells use to grow rapidly as they inside tumors dont have acess to sufficient oxygen.
