Flashcards in Ch. 12 Respiratory System Deck (78):
1

External respiration

exchange of air in lung capillaries

2

how does external respiration work

-oxygen is inhaled into the air sacs
-immediately passes into capillaries
-carbon dioxide passes from capillaries into air sacs, to be exhaled

3

Internal respiration

exchange of gases in the cells

4

how does internal respiration work

-occurs simultaneously between cells and capillaries
- oxygen passes out of the bloodstream into the tissue
-carbon dioxide passes out of tissues back into the bloodstream to travel to lungs

5

mediastinum

middle of chest where trachea divides into two branches

6

bronchi

each leads to a separate lung

7

lungs

lobes are not mirror images

8

hilum

blood vessels, nerves, lymphatic tissue

9

adenoids

lympathic tissue in the nasopharynx

10

alveolus

air sac in the lung

11

bronchioles

the smallest branches of the bronchi

12

bronchus

the branch of the trachea that is a passageway into the lung

13

carbon dioxide

exhaled through the lungs

14

cilia

thin hairs attached to mucous membrane epithelium lining the respiratory tract

15

diaphragm

contracts to pull air into the lungs
relaxes to push air out
