Human GAS EXCHANGE SYSTEM - A level Biology. Learn the structures, ventilation and gas exchange.
Learn the structure of the human gas exchange system (lungs trachea, bronchi, bronchioles and alveoli). Learn how ventilation occurs in humans and how the alveolar epithelium is adapted for efficient gas exchange (diffusion).

Do we need to know about the goblet cells, ciliated epithelium and smooth muscle for this topic?

Not for AQA Biology. 😊
at 6:24 in the bottom row, it says that air moves into the lungs and into lower pressure but then the column to the right says out of the lungs and from higher pressure. So do the lungs have a higher pressure than the atmosphere or vise versa?
@MissEstruchBiology
2 жыл бұрын
Hello, The pressure changes depending on the volume of the lungs (which changed as you inhale and exhale). The pressure is higher in than lungs compared to atmospheric when the rib cage moves in and up, but the pressure is lower in the lungs compared to the atmospheric pressure when the rib cage moves out and down.
What about the outer and inner pleural membranes. I don’t understand why the inner pleural membrane moves outwards in inspiration.
@MissEstruchBiology
3 жыл бұрын
Hello 😊 Everything moves outwards during inspiration to create a larger volume in the thorax and therefore a lower pressure so that air rushes in.

Miss help me on explaining the difference in the amounts of gases breathed in and out Thus to say nitrogen, carbon dioxide, oxygen and vapour
@MissEstruchBiology
5 ай бұрын
nitrogen won't change as it doesn't diffuse into the blood. Carbon dioxide would increase as it diffuses out of the blood into the alveoli. Oxygen would decrease as it diffuses into the blood

I'm not familiar with that exam board, but you could check with your specification ( you can get this online) while watching the video to see if it is the same level of detail you need.

Hey, I was wondering why ciliated epithelial cells have large quantities of mitocondria.
@MissEstruchBiology
3 жыл бұрын
The ciliated cell projections sway to help move mucus up and out of the lungs. This movement requires energy in the form of ATP and ATP is made in aerobic respiration in the mitochondria. I hope that helps :D
