Pulmonary System Flashcards
1
Q
Upper Respiratory System
A
- nose
- nasal cavity
- paranasal sinuses
- pharynx
2
Q
Lower Respiratory System
A
- Larynx
- Trachea
- Bronchi
- Bronchioles
- alveoli
3
Q
Pharynx
A
NASOPHARYNX (upper)
OROPHARYNX (middle)
LARYNGOPHARYNX (lower)
- supplies are to larynx and trachea
- part of digestive and respiratory
4
Q
Nasopharynx
A
- respiratory
- extends to soft palate
(top)
5
Q
Oropharynx
A
- digestive + respiratory
- soft palate to epiglottis
(middle)
6
Q
Laryngopharynx
A
- digestice + respiratory
- posterior to larynx
- epiglottis to cricoid cartilage
7
Q
Epiglottis
A
separates food from breathing
8
Q
Larynx
A
- organ of voice production
- level C3-C6
- connects pharynx and trachea
- 9 cartilages
9
Q
Larynx Cartilages
A
THYROID
- largest
- “ampitheatre”
CRICOID
- thicker / stronger
- only complete ring of cartilage
ARYTENOID
- superior to cricoid
- forms attachment for ligament
10
Q
Glottis
A
Vocal apparatus of larynx
11
Q
Rima Glottidis
A
aperture between vocal folds
shape varies according to sounds
12
Q
True Vocal cords
A
- vocal fold
- controls sound production
- consists of vocal ligament and vocalis muscle
13
Q
False Vocal Cords
A
- Vestibular fold
- extend between thyroid and arytenoid cartilage
- protective function
- space between true and false cord = ventricle of larynx
14
Q
Trachea
A
- fibrocartilagenous tube
- supported by incomplete tracheal rings
15
Q
Pleurae of lungs (2 continuous membranes)
A
- VISCERAL PLEURA
the lungs cannot be separate from lungs
- similar to pia matter
- sits up against the viscera - PARIETAL PLEURA
lines pulmonary cavity
- superficial oto visceral pleura
- parietal touches intercoastals
