Respiratory System

Question 1

Respiratory Portion includes what 4 things?

Answer 1

Respiratory bronchioles, alveolar ducts, atria and alveolar sacs

Question 2

The nose does what three things to the air that travels in it?

Answer 2

Humidifies, warms and filters

Question 3

The nose is an organ of:

Answer 3

Olfaction

Question 4

Lines the vestibule of the nose, surface is stratified squamous non-keratinized except close to the nasal openings:

Answer 4

Vestibular Mucous Membrane

Question 5

Lines the nasal cavity proper which contains three shelf-like projections called nasal conchae. The surface is made up of pseudostratified columnar ciliated with some goblet cells. Lamina propria is rich in venous plexes. Also contains serous mucous glands that moisten the mucous membranes and humidifies the air.

Answer 5

Respiratory Mucous Membrane

Question 6

Olfactory mucous membrane contains three types of cells:

Answer 6

Olfactory, Supporting (Sustentacular), and Basal Cells

Question 7

These cells (of the olfactory mucous membrane) are stem cells for the sustentacular cells:

Answer 7

Basal Cells

Question 11

What are the 4 elastic cartilages of the larynx?

Answer 11

Corniculates, cuneiforms, epiglottis, and tips of arytenoids

Question 12

Vocal cords are covered with what type of epithelium?

Answer 12

Question 15

Epithelium in the bronchioles changes from pseudostratified columnar ciliated with goblet cells into what?

Answer 15

Simple columnar ciliated without goblet cells

Question 16

Small alveolar cells that are involved in gas exchange are called what?
