19. REVIEW…
STRUCTURE FUNCTION
Trachea
(windpipe)
keeps the windpipe "open" and is lined
with fine hairs called cilia which filter
air before it reaches the lungs
bronchi
two branches at the end of the trachea,
each lead to a lung
bronchioles
a network of smaller branches leading
from the bronchi into the lung tissue &
ultimately to air sacs
alveoli
the functional respiratory units in the
lung where gases are exchanged
23. Checking your Understanding
Which of the following sites would be the most
lethal if obstructed by a foreign body?
a. Right bronchus
b. Left bronchus
c. Trachea
ANSWER:
26. External Respiration
Gas exchange between blood and air at alveoli.
O2 (oxygen) in air diffuses into blood.
CO2 (carbon dioxide) in blood diffuses into air.
27. Brings O2 from lungs cells of the body.
Takes CO2 from the cells throughout the body and
return to the lungs to be exhaled.
Transport of
Respiratory Gases
28. Gas exchange in capillaries between blood and tissue
cells.
O2 in blood diffuses into tissues.
CO2 waste in tissues diffuses into blood.
Internal Respiration
30. What is a Respiratory Volume?
Different volumes of air move in and out of
lungs with different intensities of breathing.
31.
32. Respiratory Volumes
Amount of air that moves in or
out of the lungs during a normal
breath
Amount of air that can be
forcefully inhaled following a
normal inhalation
Amount of air that can be
forcefully exhaled following a
normal exhalation
Tidal Volume

Volume
33. Respiratory Volumes (cont.)

can hold
Residual
Volume
