Question 36

Compare and contrast the birds respiratory system to that of a mammal

Answer 36

A birds respiratory system pumps air into the lungs using expansion and contraction of the thoracic cavity by the chest muscles rather than using a diaphragm as mammal do. This allows birds to breathe more vigorously during flight when they need the most oxygen. A bird’s lungs have air capillaries that allow air to flow straight through unlike mammalian lungs which have dead end alveoli. Air travels to the lungs rather than in and out of them. Birds have air sacs for storage, unlike mammals. Air tubes connect the air sacs to the hollow these type of chicks are featherless and helpless when they hatcavities of the bones. A bird inhales and exhales twice to move each breath through the respiratory system, unlike a mammal which inhales and exhales once for each breath.
