Yes. Bird lungs are more efficient than mammal lungs.
They connect to air sacks in the body and bones. This makes them more efficient that mammal lungs.
because their lungs are smaller and they have more organs to pump blood through
Gills are more efficient at obtaining oxygen, but there is much more oxygen in air to breath through the lungs.
When the bird breaths in, the oxygen stays in there air sacs, but when humans breath in, the oxygen doesnt stay in the air sacs, it has a gas exchange in the alvioli and the oxygen goes into the blood stream
According to my college biology professor, birds have the most efficient lungs of all LAND vertebrates.
Amphibian lungs do not have to be as efficient as gills because there is much more oxygen in air than in water.
They are hollow (for lightness) and have air sacks connected to the lungs (this makes the lungs more efficient).
Cappilarisation is where the capillaries in the lungs and surrounding the alveoli increase in numbers, making gaseous exchange in the lungs more efficient so that the respiratory system is more efficient gnereally and during exercise, meaning the heart does not have to work at a higher level to supply nutrients and oxygen to muscles and organs.
Being extinct, Tasmanian tigers no longer breathe at all. This animal, more properly known as the thylacine, was a mammal, so it did breathe air using lungs.
it is a mammal because it has warm blood and breaths, doesn't hatch out of egg... remember all this stuff so you can tell apart mammals more easy
The possession of four pulmonary veins, along with the fact that a bird's heart is generally larger and more muscular per pound (or kilogram) or body weight than ours, explains why a bird's circulatory system is more efficient than ours. The left ventricle in a bird's heart is by far the largest chamber and has to work exceptionally hard in small birds which have hovering flight such as humming birds.
The ailurus fulgens is a herbivorous mammal.
