Breathing is something we do without thinking about it and without any effort. But did you ever question yourself about the science behind this? Well, I thought it could be interesting to learn the ventilatory mechanism that helps us breathe, and I found the perfect infographic to illustrate it, along with two other species.
Three species very different from one another
Created by Eleanor Lutz, a designer with a Bachelor’s in molecular biology and the owner of the blog TableTop Whale, the infographic shows the respiratory system of three different species: human, bird, and grasshopper. Ms. Lutz chose those species because she thought they were pretty special to observe, and I completely agree with her. It’s really amazing to see how completely different they are from one another.
Those three species don’t breathe the same way at all. While humans have a pressure lower than the outside environment, birds store the air in sacks, and this enables them to inhale oxygen while exhaling. Something that really surprised me is that grasshoppers don’t have lungs. Instead, they transport air straight from the tracheal tubes to the tissue cells. That’s pretty awesome!
See the three respiratory systems in action
To see the three respiratory systems in action, check out the infographic below. You will be amazed by the way nature made us so very different, yet each species has a ventilatory mechanism perfectly adapted to its needs. Once again, this is proof that nature does things very well!
