New cards

respiratory system function

Bring oxygen to and eliminates carbon dioxide from the blood.

2
New cards

breathing (inhaling or exhaling)

The process of bringing oxygen into the lungs

3
New cards

ventilation

exchanging the gas oxygen with the gas carbon dioxide in the lungs

YOUTBUBE THE FLOW OF THE RESPIRATORY SYSTEM!!!!

airs enter through:

-nasal openings

-moves into nasal cavity

-travels past the pharynx (throat)

-into the trachea

-divides into right and left primary bronchi

-right bronchus continues to the right lungs

-left bronchus continues into the left lungs

-right and left bronchi subdivides into smaller tubes called bronchioles.

-bronchioles terminated in alveoli
