|
trechea
|
in vertebrates tube that carries air from the nasal passages or mouth to lungs also known as windpipe

Alveoli
|
gas exchange structure within mammalian lungs tiny air pocket with walls made of a membrane that is a single cell thick allowing for exchange of respitoary gasses.
|
|
bronchiole
|
the passage way that branches from the treachea into the lungs, with one bronchus carrying air into each lung

|
muscular layer that seperates the region of the lungs, from the region of the stomach and liver
|
|
epiglottis
|
flap of cartilage located over the entrance to the trechea. closes during swallowing to prevent food from entering the respitory tract.

|
|
residual volume
|
amount of gas that remains in the lungs and the passageways of the respitoary system even after full exhalation
