Marieb, Jon B. Mallatt, Patricia Brady Wilhelm 1,433 solutions Mammals: Breve with lungs Mammals have a two-way breathing system which uses a diaphragm to pump air in and out of their lungs. Mammal lungs branch extensively, and their entire volume is filled with bubble like structures called alveoli. Mammals have the greatest lawn service area among animals. Birds: Breve with lungs In birds the lungs are structured so that the air flows mostly in only one direction. No stale air gets trapped in the system. A unique system of tubes air sacs in birds respiratory system enabled this one way airflow thus the gas exchange surfaces are constantly in contact with fresh air. Insects: In most insects a system of tracheal tubes extend throughout the body. Air enters and leaves the system through openings in the body surface called spiracles. In some insects, oxygen and carbon dioxide die fuse through the tracheal system, And in and out of body fluids in other insects body movements help pump air in and out of the tracheal system. What makes bird respiratory system so efficient?Birds breathe with greater efficiency than humans because of the structure of their lungs --looped airways that facilitate air flows that go in one direction -- a team of researchers has found.
Why the respiratory system of birds is more efficient than in mammals?The air capillaries in the walls of the parabronchial system have a much larger overall surface area than that found in the mammalian respiratory system. The greater surface area allows a greater proportion of oxygen from each breath to be exchanged for carbon dioxide from the blood and tissues.
Why are birds lungs more efficient than human beings?Birds breathe with greater efficiency than humans due to the structure of their lungs—looped airways that facilitate air flows that go in one direction—a team of researchers has found through a series of lab experiments and simulations. The findings appear in the journal Physical Review Letters.
