    Thank you so much for this video. I have was having a hard time visualising all the different parts of the insect but this video made it so easy to visualise and understand!

    I thought an insect would have a large surface area compared to their volume??? and larger organisms have a small surface area to volume ratio.

      Compared to humans, it has a large SA:V, but compared to bacteria, which is probably the video prior to this, insects have a smaller SA:V

  • @mistarizla
    @mistarizla 9 ปีที่แล้ว +1

    Does movement of the insects muscles create a mass movement of air in and out out of the trachea, thus speeding up gaseous exchange?

    • @MrPollockBiology
      @MrPollockBiology  9 ปีที่แล้ว +1

      Yes the pumping of the abdomen does ventilate the insect quicker. I wouldn't say it speeds up gas exchange though...it's more to help the insect meet the increased oxygen demands of respiring tissues during exertion.

    Mr. Pollock... How do the insects not have bacteria growing like crazy in their wet breathing tubes????????? they are literally crawling through their own filth often... you would think infections would be killing them constantly.

    • @MrPollockBiology
      @MrPollockBiology  9 ปีที่แล้ว +1

      Omar, in Biology we must think about SA:V as relative. Whilst I agree that insects will have a large sa:v relative to a human, they will have a small sa:v relative to a bacterium. In this video we are considering the implications of surface area and volume upon gas exchange. Any organism which has a dedicated gas exchange surface does so because it is unable to exchange directly with its environment, because the demands of its cells are too high. It therefore follows, that any organism with an internal exchange surface does so because it's SA:V is too small to allow exchange through its surface. I hope that helps

    @mattn1388 3 ปีที่แล้ว

    You say small surface area, large volume. I disagree with this because small animals have high surface area, low volume, ratio, which allows them to be without lungs. Where as an elephant has a large volume and lower SA and obviously needs lung
