1. what is the func- warms, filters and moistens the air
tion of the nose?
2. phranyx throat, space between the nose and mouth, passageway for food, drink, and air.
COnnected to the middle way via auditory (Eustachian) tubes.
3. Larynx Adam's apple, boxlike structure made primarily of cartilage, entrance to lower
respiratory system, source of voice.
4. Trachea windpipe, and bronchial tree. Tube held open by C-shaped rings of cartilage
(collapsing), allows food to go down. Trachea divides into two tubes called the
primary bronchi, each of which leads to a lung. Bronchioles terminate in alveoli,
sacs for gas exchange (grapes).
5. Alveoli minute sacs where oxygen and carbon dioxide diffusion. Phospholipid molecules
that coat alveoli and keep them open.

6. How does air Due to the changes in the thoracic cavity. Air moves into lungs when pressure in
pressure change? atmosphere is greater than pressure in lungs and air moves out of lungs when
pressure in lungs is greater than pressure in atmosphere.
7. tidal volume Amount of air that moves in (inhale) and out of the lungs (exhale) during a normal
breath
8. inspiratory re- Amount of air that can be forcefully inhaled after a normal tidal volume inhalation.
serve volume
9. expiratory re- Amount of air that can be forcefully exhaled after a normal tidal volume exhalation
serve volume (swimming)
10. vital capacity The total volume of air that can be exhaled after maximal inhalation.
11. residual volume Amount of air remaining in the lungs after a forced exhalation
12. total lung capaci- vital capacity + residual volume, total volume of air in lungs after maximal inhala-
ty tion.
13. 3 processes that 1. external respiration (occurs in alveoli, oxygen diffuses into blood and carbon
transport gases dioxide diffuses from blood)
between lungs 2. Gas transport by the blood
and cells 3. Internal respiration (occurs in tissues, oxygen diffuses out of blood and into
cells, and carbon dioxide diffuses out of cells and into blood).
14. Carbon dioxide is 1. dissolved in blood plasma
removed by the 2. carried by hemoglobin
blood in one of 3. most of carbon dioxide transport as a bicarbonate ion.
three ways
15. 2 types of diges- mechanical- physical breaking of food into smaller pieces (occurs by teeth and
tion tongue)
