1

What is another name for Inhalation?

Insporation

2

No, The lungs PASSIVELY bring air into them. This happens when the diaphram contracts pulling/expanding the lungs and because "Boyle's law" air enters the lungs.

3

What does the upper respiratory tract consist of?

- Nasal cavity - Pharynx

4

What does the Lower respiratory tract consist of?

Larynx, Trachea, Bronchi ----> Alveoli

5

What are the 4 functions of the UPPER respiratory tract?

1. Warm & Humidify air 2. Remove pathogens 3. Olfaction 4. Serves as a trap to drain out paranasal sinuses & Lacrimal ducts

6

What do the Turbinates do and how many are there?

Turbinates force air into a regular steady flow over mucosal surfaces. - 3 - (Superior, Middle & Inferior)

7

Another name for Respiratory of Epithelium

Pseudostratified Ciliated Epithelium

8

What structures/cells are found in Olfactory epithelium?

Specialized epithelium STILL pseudostratifed. found in superior turbinate and roof of nasal cavity

9

What are some functions of the Larynx

AKA voice box! Protection also serves as gate for GI an d respiratory passages.
