Bird lungs are efficient because of

WebThe bird lung is very efficient partly because of an extremely thin blood-gas barrier so that some birds have thinner barriers than any mammals. We show here that in addition to the total barrier being very thin, the interstitium which is responsible for the barrier's strength is extraordinarily thin. This observation is paradoxical because ... WebFeb 7, 2013 · Because the lungs are fixed volume (~1.4% volume change during the respiratory cycle) the capillaries are not mechanically stressed and their cell walls are extremely thin. So birds have a larger surface area per unit volume of lung and thinner barriers to gas diffusion.

WebAlso, birds sometimes fly very high up, where there is very little oxygen in the air. Birds can fly up that high without any help, because of their special lungs. The bird's respiratory system takes up 20% of a birds's volume (our respiratory system takes up only 5% of our volume). Birds breath much more rapidly than humans do. WebNov 13, 2015 · Birds are capable of high rates of gas exchange because of the special construction of their lungs, and additional breathing organs, a complex series of air sacs. Connecting tubes join the lungs to these air sacs, increasing a bird's respiratory capacity to about twice that of any mammal of comparable size.

Why do birds have the most efficient respiratory system?

WebMost amphibians have lungs that are less efficient than other vertebrates for which of the following reasons? They are simple sacs with little surface area The respiratory system that involves diffusion of oxygen and carbon dioxide directly into and out of cells is the tracheal system of insects. WebBirds must be capable of high rates of gas exchange because their oxygen consumption at rest is higher than that of all other vertebrates, including mammals, and it increases many times during flight. The gas volume of the bird lung is small compared with that of mammals, but the lung is connected to voluminous air sacs by a series of tubes, making …
