Function
Driving area (filter,
heat, humidify the
air and brings it to
the lungs)
Respiratory tract
(tissue inside the
lungs where gas
exchange occurs
Function 1: produce
mucus
Resonance chambers
for sound when we
talk.
Function 2:
Heating,
humidification and
filtration of inhaled
air.
Coated with
skeletal
muscle and
mucosa
Funnel
shaped
canal.
• 13 cm long
• Through
passage of
air and
food
It is divided into
three regions:
nasopharynx
oropharynx and
laryngopharynx
The most
important
arytenoid
(influence
changes in
position and
tension of the
vocal folds).
Connect the
laryngopharynx
to the trachea.
Made up of 9
pieces of
cartilage

GAS
EXCHANGE
1) Gas exchange
2) Vocalization
3) Excretion
4) Defense
5) pH regulation
1) It provides oxygen to the bloodstream
and removes carbon dioxide
2) It enables sound production or vocalization as
expired air passes over the vocal cords.
3) It assists in abdominal compression during
urination, defecation, and childbirth.
4) It enables protective barriers, like the coughing
and sneezing, to keep the air ways free of
strange agents.
5) CO2 reacts with H2O into the organism to
become bicarbonate which prevents a state
of acidosis in the body.
Pulmonary
Ventilation
Internal
respiration
External
respiration
Gas
Transport
• The air should enter and exit to
the lung.
• Is a mechanical process.
• Is renamed respiration
Back
• Gas exchange
take place to
between to
alveoli and
pulmonary blood
What
happens?
Differences
• Carbon dioxide:
dark red blood
• Oxygen: scarlet
river
• Oxygen
uptake by
hemoglobin
Back
oxygen and carbon
dioxide
travel
through the blood
Gas
transport
oxygen
binds
to
hemoglobin
mo
lecules,
carbon dioxide is
transported in plasma
as
bicarbonate ion
Back
gas exchange must
be
made
between
blood
and tissue cells.
