What are the parts of respiratory system in aves?

Answer 1

a. Nose -Inspiration and expiration usually occurs through the nose. The nose has main two functions: The cilia and hairs which line the nasal cavities trap dust and other foreign particles and the rich supply of blood surrounding the cavities warms the air before it enters the lungs.

b. Pharynx - allows for separation of food and air. The epiglottis closes the trachea when we eat and opens when we breathe.

c. Larynx - this structure sits on top of the trachea. Air rushing across two ligaments causes sounds that we shape into speech. Also called the voice box.

d. Trachea - Also called the windpipe

e. Bronchi - the trachea branches into two forks each called a bronchi

f. Bronchioles - the smaller and smaller passageways that come off the bronchi

g. Alveoli - these are the small air sacs where actual gas exchange takes place.
