NERVOUS SYSTEM AND SPECIAL SENSES,RESPIRATORY SYSTEM Flashcards
considerably larger in
birds than in reptiles but are almost homologous to the
mammalian basal nuclei.
cerebral hemispheres
Two bones, are
found in the middle ear,
columella and stapes
FUNCTION OF RESPIRATORY SYSTEM
*Gas exchange
*Regulation of body temperature
* Vocalization
* Flight adaptation
*Buoyancy and stability
* Filtering of airborne particles
*Storage of air
*Birds have a________ air sac located in the neck
region and body cavity that functions to inflate the
lungs.
*Birds have a nine air sac located in the neck
region and body cavity that functions to inflate the
lungs.
when the bird breathes in, air bypasses the lungs
and enters the posterior air sacs. At the same time, the air in the
lungs from the last exhalation phase exits the lungs and enters
the anterior air sacs.
Inhalation
bird releases air from the posterior air sacs, which
enter the lungs. The air that fills the anterior air sacs from
the inhalation phase is then released from the body through the
trachea.
Exhalation
It Purpose is
passageway for air
to be breathed in
and out of the
trachea.
