Location and Function of respiratory system organs Flashcards
Nasal cavity
Nose
Brings in Air
The mucus block dirt and some bacteria from getting in
Epiglottis
In throat behind tongue
Prevents liquid from entering the lungs
Pharynx
In the middle of your neck
Routes air coming in your nose and mouth down to your larynx (voice box)
Larynx
Middle of neck
The larynx allows air to pass from your throat to your trachea and on to your lungs . It also contains the vocal cords, which create sound when air passes through them.
Trachea (windpipe)
Lower neck/upper chest
Creates a passage for air, moistens and warms it while it passes into the lungs
Bronchi
Lungs
Your bronchi carry air to and from your lungs.
Bronchioles
Lungs
The bronchioles are part of the lower respiratory system and are responsible for delivering air to a diffuse network of around 300 million alveoli in the lungs.
Aveoli
Lungs
They expand during inhalation, taking in oxygen, and shrink during exhalation, expelling carbon dioxide. These tiny air sacs are the site where gas exchange happens,
