    Video's like this take concepts that are not actually complicated, but a little difficult to comprehend from just reading for some people and make them seem much more simple! Thank you!

    You forgot to say how surfactant help alveoli from collapsing. It is in my physics book. They basically talk about how there are many size of alveoli. Pressure is indirectly related to radius of the bubble(alveoli) and directly related with surface tension of the bubble, which basically means that bigger bubble has low pressure than smaller bubble and also high surface tension means high pressure . Basically as small alveoli has greater pressure, air from it will move to lower pressure big bubbles, collapsing smaller bubble due to difference in pressure(diffusion occurs). Surfactant reduces surfaces tension. Thus less difference in pressure.

    The systolic pressure in a major artery is measured at
    115 mmHg. What is the net force on a 1 cm2
    section of the arterial
    wall if the (absolute) pressure in the tissue outside the arterial
    wall is 109 kPa? (Patm = 101.3 kPa)

    it is true that they help in expantion but how they help in preventing constricting because if we remove surface tention from water baloon its wall will constrict and baloon will break.

    A patient is presented with pneumonia type symptoms except mucus is watery... It's water, clear and not thick. We have exhausted all options of antibiotics. Patient currently given corticosteroids as a last ditch and is on a mechanical ventilator with oxygen levels of 70%. She has reactive type 2 pneumocytes. Ps: I am not a nurse... I am a concerned daughter looking for answers and hope as our medical system is primitive and they don't know what reactive type 2 is. Can anyone help please. Are there any other ideas we can try? Would proning help relieve any pressure on her lungs Thanks in advance. From New Zealand.
