1

Define the primary function of the respiratory system?

Exchange gases (oxygen and carbon dioxide)

2

Define the secondary function(s) of the respiratory system?

Produce vocal sound, sense of smell, maintain homeostasis (regulation of pH and reflexes), low pressure pump, and emotions.

3

Respiration?

Process of gas exchange

4

Ventilation?

The movement of air into the lungs.

5

Explain the four main stages of respiration.

1. Ventilation

2. Gas exchange between blood and air (external respiration)

3. Gas transport in the blood

4. Gas exchange between blood and body cells (internal respiration)

6

Cellular Respiration

Oxygen use and carbon dioxide production at a cellular level.

7

Define the three organs of the upper respiratory system

Nasal cavity, larynx, and pharynx

8

Define the three organs of the lower respiratory system

Lungs, bronchioles, and alveoli

9

Describe the formation and functions of the nose.

Bones and cartilage support the nose, two openings (nostrils), vibrissae filter large particles, olfactory mucosa, respiratory mucosa.

10

Nasal Cavity?

Hollow space behind the nose

11

Nasal Septum?

Vomer and ethmoid

13

Deviated Nasal Septum?

When the septum bends to one side

14

Nasal Conche?

Bone that divides the nasal cavity, support the mucus membrane and increase surface area (superior, middle, and inferior)

15

What is the function of the conche?

Increases surface area
