6.3: Anatomy & Physiology: Respiratory System 🫁 Flashcards
Respiratory System
Brings in oxygen and releases carbon dioxide. It also helps regular pH levels.
Upper Airway
- Nose & Mouth
- Nasopharynx
- Oropharynx
- Larynx
- Epiglottis
Upper Airway: Nasopharynx
The upper part of the throat is behind the nose. (think of naso as nasal)
Upper Airway: Oropharynx
The area of the throat behind the mouth. (think of oro as oral/mouth)
Upper Airway: Larynx
Voice Box.
Upper Airway: Epiglottis
The valve that protects the opening of the trachea.
Pharynx
The throat.
FBAO
Foreign-body airway obstruction.
Lower Airway
- Trachea
- Carina - (kuh-ree-nuh)
- Left & Right Bronchi
- Bronchioles - (brawk-ee-oles)
- Alveoli - (al-vee-uh-lie)
Lower Airway: Trachea
Long tube (aka windpipe) that connects the Larynx to the Bronchi
Lower Airway: Carina (kuh-ree-nuh)
Where the trachea branches into the left and right into the bronchi.
Lower Airway: Bronchi (brawnk-eye)
Tubes that lead the trachea to both lungs.
Lower Airway: Bronchioles (brawnk-ee-oles)
Small branches of the Bronchi. (think mini)
Lower Airway: Alveoli (al-vee-uh-lie)
Tiny air sacs of the lungs that exchange oxygen and carbon dioxide.
Pleura
Two thin, smooth layers of tissue with a thin film of fluid between the lungs.
