Respiratory System Anatomy Flashcards
Nasal concha
bony elements forming the upper chambers of the nasal cavities
Eustachian tube
an opening that connects the middle ear with the nasal-sinus cavity.
- This tube helps to balance pressure in the middle ear
Sinuses
Air pockets in skull
Pharynx
Nose and mouth are connected
Epiglottis
flap that covers the larynx when swallowing
Larynx
- a hollow tube in the middle of your neck, just above your trachea (windpipe) and behind your esophagus. It makes it possible for you to make sounds, which is why it’s also called your voice box.
- attaches to hyoid bone
Thyroid Cartilage
- on top of larynx
- Adam’s apple in males
- large shield shaped cartilage
Cricoid Cartilage
- ring for intubation *movement
- below adam’s apple
Trachea
- 4 -6 inches long
- made of tracheal cartilage
Purpose of Cartilagenous Rings in Trachea
- keep the trachea open as it would otherwise naturally cave in
Carina
- where trachea splits
- NEVER touch it because there is a cough trigger on it
Bronchus
a passage or airway in the lower respiratory tract that conducts air into the lungs and split from mainstem bronchus which splits from trachea
Boyle’s Law
a gas law, stating that the pressure and volume of a gas have an inverse relationship
Diaphgram
muscle that is used for ventilation and is made of skeletal muscle
When contracting or breathing in with your diaphgram, what happens to volume and pressure?
Volume increases
Pressure decrease
