The epithelial lining of TBT is primarily composed of:
Pseudostratified ciliated coumnar epithelium (PSCC)
- are more numerous in the left lung than the right

During inspiration, the vocal cords
- move apart
fibrocartilaginous structure that makes up the upper part of the larynx that prevents aspiration of foods and liquids by covering the opening of the larynx during swallowing
lung cells that form the alveolar epithelium
cells found in the intra-alveolar septa in the lamina propria that play an important role in the immunologic response mechanism by degranulating and releasing chemical mediators such as histamine and leurkotrienes
single cartilage inferior to the thyroid cartilage that forms the majority of the posterior wall of the larynx
submucosal layer of the tracheobronchial tree composed of fibrous tissue that houses blood vessels, nerves, lympathic vessels and smooth muscle fibers
functional portion of the lungs made up of the alveoli
gel-like substance held toghether by collagen fibers thta supports the alveolar-capillary membrane.Â Composed of tight and loose space
The length of the trachea is about:
11-13 cm long
parts of the sternum
- Xiphoid Process
inspiratory accessory muscles include
1. Scalene muscles
2. Sternocleidomastoid muscles
4. Pectoralis major muscles
5. Trapezius muscles
Goblet Cells/Submucosal Glands
Most of the mucus that lines the lumen of the tracheobronchial tree is produced by the:
Cartilage is present in the following structures of the TBT?
1. Lobar bronchi
2. Subsegmental bronchi
3. Segmental bronchi

the left side of the lung has how many fissures
The RIGH lung has how many lobe
the RIGHT side of the lung has how many fissures
The bronchial blood supply originates in this GREAT vessel
Sympathetic Nerves carry Epinephrine that has this effect on the bronchioles
Dilates the bronchioles so the patient can breath more easily
Describe the path of a dust particle from the NOSE to the alveoli
(The Mice Love Sunny Sandy Beaches They Run All Around)
Nasal Cavity →
Main Bronchus →
Lobar Bronchiole →
Segmental Bronchus →

Describe the shape and function of cartilage that makes up the trachea?
"C" rings of cartilage strengthen the trachea so that it
does not collapse, but remains open so that air can get through
If It didn't it would collapse in on itself and you would be unable to breathe.
Do the respiratory bronchioles have cartilage? Why or why not?
Bronchioles only have cartilage from the pulmonary arteries & capillaries
what are the main 4 groups of the sinuses
- ethmoid spheroid
What are the sinuses functions
- produce mucous from the nasal cavity
- A resonating chamber for the production of sound
- Communicator for the nasal cavity
