I. RESPIRATORY SYSTEM<\/strong><\/p>\n

A. Definitions<\/p>\n

1. Upper vs lower<\/p>\n

Upper is pathway taking air to lungs, lower is lung and its contents<\/em><\/p>\n

2. External vs internal vs cellular<\/p>\n

External is between lungs\/blood, internal is between blood\/cells, cellular is utilization of oxygen by cells<\/em><\/p>\n

B. Organs<\/p>\n

1. Nose and nasal cavity<\/strong><\/p>\n

a. External nares =\u00a0Nostrils<\/em><\/p>\n

b. Nasal septum<\/p>\n

1. Vomer<\/p>\n

2. Perpendicular plate – ethmoid<\/p>\n

3. Cartilage<\/p>\n

c. Boundaries<\/p>\n

1. Lateral & Superior<\/p>\n

-Ethmoid<\/p>\n

-Maxillae<\/p>\n

-Nasal<\/p>\n

-Frontal<\/p>\n

-Sphenoid<\/p>\n

2.\u00a0Floor<\/p>\n

-Hard palate (palatine process, palatine<\/p>\n

bones)<\/p>\n

d. Internal nares<\/p>\n

Posterior boundary of nasal cavity<\/em><\/p>\n

e. Paranasal sinuses<\/p>\n

Cavities in skull bones that communicate with nasal cavity – frontal, maxillary, ethmoidal, sphenoidal<\/em><\/p>\n

f. Superior, middle, inferior meatuses (grooves)<\/p>\n

& Conchae (shelves-extend from lateral walls)<\/p>\n

g. Function<\/p>\n

1. Warm, filter, moisten air<\/p>\n

2. Smell<\/p>\n

3. Mucus<\/p>\n

4. Resonate sound<\/p>\n

2. Pharynx<\/strong>[common to GI & resp]\n

a. Nasopharynx<\/strong>(internal nares-soft palate)<\/p>\n

1. Eustachian tubes = Auditory tubes<\/strong><\/p>\n

Connect nasopharynx with middle ear<\/em><\/p>\n

2. 1 tonsil (adenoid)<\/p>\n

b. Oropharynx<\/strong>(soft palate-hyoid)<\/p>\n

1. 2 pairs of tonsils (palatine, lingual)<\/p>\n

2. Uvula<\/p>\n

Flap dangling from soft palate, lymphatic function<\/em><\/p>\n

c. Laryngopharynx<\/strong>(hyoid-larynx)<\/p>\n

3. Larynx<\/strong><\/p>\n

a. Cartilages<\/p>\n

1. Thyroid<\/p>\n

2. Epiglottis<\/p>\n

3. Cricoid<\/p>\n

4. 2 Arytenoid<\/p>\n

5. 2 Corniculate<\/p>\n

6. 2 Cuneiform<\/p>\n

b. Mucous membranes<\/p>\n

1. Ventricular = Vestibular folds (false-upper)<\/p>\n

2. Vocal folds (true-lower)<\/p>\n

3. Glottis<\/p>\n

Actual opening in larynx<\/em><\/p>\n

4. Voice<\/p>\n

Vibration of vocal folds, resonating chambers, muscles for enunciation<\/em><\/p>\n

4. Trachea<\/strong><\/p>\n

a. Carina<\/p>\n

Inferior end of trachea<\/em><\/p>\n

5. Bronchi<\/strong><\/p>\n

– Bronchial tree<\/p>\n

a. Primary bronchi<\/p>\n

Enter lungs, cartilaginous rings<\/em><\/p>\n

b. Secondary<\/p>\n

Enter lung lobes, less cartilage<\/em><\/p>\n

c. Tertiary<\/p>\n

Branch within lobes<\/em><\/p>\n

d. Bronchioles<\/strong><\/p>\n

No cartilage in walls, replaced by smooth muscle<\/em><\/p>\n

e. Terminal bronchioles<\/p>\n

Last airway leading to air sacs called alveoli<\/em><\/p>\n

6. Lungs<\/strong><\/p>\n

a. Membranes<\/p>\n

1. Parietal pleura<\/strong><\/p>\n

Shiny lining of thoracic cavity<\/em><\/p>\n

2. Visceral pleura<\/strong><\/p>\n

Shiny lung covering<\/em><\/p>\n

3. Pleural cavity<\/p>\n

b. Gross anatomy<\/p>\n

1. Apex<\/p>\n

Superior<\/em><\/p>\n

2. Base<\/p>\n

Inferior<\/em><\/p>\n

3. Costal surface<\/p>\n

Towards rib<\/em><\/p>\n

4. Mediastinal surface –Mediastinum<\/strong>-Medial<\/em><\/p>\n

5. Hilus<\/p>\n

Area where bronchi, blood vessels enter\/exit lung<\/em><\/p>\n

6. Lobes (L-2; R-3)<\/p>\n

c. Microstructure<\/p>\n

1. Alveolus\/Alveoli<\/strong><\/p>\n

About 300 million total for great surface area<\/em><\/p>\n

2. Alveolar-capillary membrane<\/p>\n

Thin! Diffusion!<\/em><\/p>\n
