WebBecause their air sacs squeeze into the skeleton, respiratory infections have an easier time infiltrating the bones and bodies of birds. And because their lungs are SO much more efficient, birds are more vulnerable to airborne pollutants or toxins. The "canary in the coal mine" will die before any coal miners die precisely because the canary is ...

Why do birds have the most efficient respiratory system?
WebJul 10, 2024 · 10. One of the quickest ways to increase the efficiency of the cardio-vascular system is to take EPO/use blood doping. So, it seems the lungs and heart are already big enough to utilise more oxygen carrying capacity than our blood already has. You ought to be looking at increasing the efficiency of the blood. WebBirds are a group of warm-blooded vertebrates constituting the class Aves (/ ˈ eɪ v iː z /), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton.Birds live worldwide and range in size from the 5.5 cm (2.2 in) bee hummingbird to the 2.8 m (9 ft 2 … t-test psychology
