As cells use oxygen, they release ______ ________, a waste product that the body must get rid of. These oxygen-using cellular processes, collectively referred to as __________ ___________.

-Carbon dioxide
-Cellular resipration

2

The major role of the respiratory system is to...

supply the body with oxygen and dispose of carbon dioxide

3

Four distinct processes, collectively referrred to as _________ must occur.

-respiration

4

The 4 four distinct processes of respiration are:

-Pulmonary ventilation
-External respiration
-Transport of respiratory gases
-Internal respiration

5

The tidelike movement of air into and out of the lungs so that the gases in the alveoli are continuously changed and refreshed. AKA: ventilation or breathing.

Pulmonary ventilation

6

The O2 and CO2 exchange between the lungs and blood (oxygen loading/carbon dioxide unloading)

External respiration

7

The ________ ___ _______ _______ between the lungs and tissue cells of the body accomplished by the cardiovascular system, using blood as the transport vehicle.

Transport of respiratory gases

8

Exchange of O2 and CO2 between systemic blood vessels and tissue cells. (oxygen unloading and carbon dioxide loading)

Internal respiration

9

Respiratory System

-Pulmonary ventilation
-External respiration

10

Circulatory System

-Transport of respiratory gases
-Internal respiration

11

The nasal passage are separated from the oral cavity below by a partition composed of _________ & ___________.

hard palate
soft palate

12

site of gas exchange

respiratory zone

13

conduits to gas exchange sites

conducting zone

14

Diaphragm and other muscles that promote ventilation

Respiratory muscles

15

Commonly called the throat

the funnel shaped pharynx

16

Consists of 9 cartilages, 2 prominent are the thyroid cartilage and cricoid cartilage.

larynx

17

Thyroid cartilage with laryngeal prominence is commonly referred to as the ________ _______.

Adam's Apple

18

All of the laryngeal cartilages are composed of hyaline cartilage except the flaplike __________.

Epiglottis

19

The mucous membrane of the larynx is thrown into 2 pairs of folds, the upper ________ _________ and the lower _________ _________.

vestibular folds, vocal folds

20

The upper vestibular folds are also called the

false vocal cords

21

The lower vocal cords are also called the

true vocal cords

22

Vibrate with excelled air for speech

true vocal cords

23

The slitlike passageway between vocal folds

glottis

24

Trachea is the

windpipe

25

Cricoid cartilage is _______ shaped.

Ring

26

Elastic cartilage covers laryngeal inlet during swallowing

epiglottis

27

The continuous branching of the respiratory passageways in the lungs

Bronchial respiratory tree

28

The right and left main bronchi plunge into their respective lungs at an indented area called _________.

hilum

29

Where O2 enters blood, O2 and CO2 exchange

alveoli

30

The walls of the trachea are reinforced with ________ cartilaginous rings

c-shaped

31

Tiny balloon like expansions along the alveolar sacs

Alveoli

32

Terminate in alveolar sacs that rather resemble clusters of grapes.

Alveolar ducts

33

The air blood barrier

respiratory membrane

34

Covering, no rubbing when lungs move

pluera

35

The outer layer is the ________ pleura. Is attached the thoracic walls in the diaphragm (closer to rib)

parietal

36

The inner layer covering the lung tissue is the _________ pleura. Touches organ/lung.

Parietal
