16
Q

Trachea

A

windpipe; smooth muscle w/ c-shaped rings of cartilage allows food to travel to esophagus easier, lined w/ cilia & mucus; path of air from larynx to bronchi

17
Q

Primary bronchi

A

left & right branch off trachea; lined w/ cilia, supported by cartilage

18
Q

Secondary bronchi

A

branch off of primary bronchi

19
Q

Tertiary bronchi

A

branch off of secondary bronchi

20
Q

Bronchioles

A

branch off of tertiary bronchi

21
Q

Terminal bronchioles

A

First division on the bronchioles

22
Q

Respiratory bronchioles

A

Last division on the bronchioles

23
Q

Lungs

A

principal organs of respiration; right lung 3 lobes, left lung 2 lobes

24
Q

Alveoli

A

Extremely thin-walled sacs covered w/ capillaries; actual site of gas exchange

25
Q

Diaphragm

A

large breathing muscle; moves down (contracts) when you inhale, moves up (relaxes) when you exhale

26
Q

uvula

A

blocks passageway to nasal cavity so that food doesn’t enter nasal passage

27
Q

Inspiration

A

Breathing in; Diaphragm contracts & lowers; increasing volume, decreases pressure.

28
Q

Expiration

A

Breathing out; Diaphragm relaxes & raises; increased pressure, decreases volume

29
Q

External Respiration

A

converts deoxygenated blood to oxygenated blood; air from lungs to blood; efficient b/c thin membranes, large surface area, & narrow capillaries

30
Q

Respiratory membrane

A

Actual site of gas exchange
