respiratory Flashcards
- consists of the nose,
pharynx, larynx,
trachea, bronchi,
bronchioles, & lungs
The Respiratory System
allows O2 from the air to enter the blood & CO2
to leave the blood & enter the air
Gas Exchange
the respiratory &
cardiovascular systems work together to supply O2
to all cells and to remove CO2
Gas Exchange
alters blood pH by changing blood CO2
levels
Regulation of blood pH
air movement past the vocal folds
produces sound
Voice production
nasal cavity contains olfactory
receptors
Olfaction
provides protection against some
microorganisms by preventing
their entry into the body & by
removing them from respiratory
surfaces
Protection
refers to the entire
process of gas
exchange between the
atmosphere & the cells
RESPIRATION
or “breathing”
Ventilation
refers to the flow of air
into and out of
the lungs
Ventilation
is gas exchange bet.
the alveoli & the
blood in pulmonary
capillaries
External Respiration
an exchange with the
“external”
environment
External Respiration
pulmonary capillary
blood gains O2 &
loses CO2
External Respiration
is gas exchange bet.
the tissue cells & the
blood in the
systemic capillaries
Internal Respiration
the blood loses O2 &
gains CO2
Internal Respiration
includes the nose, nasal
cavity, pharynx, &
associated structures
Upper Respiratory Tract
prepares the air for entry
into the lower respiratory
tract
Upper Respiratory Tract
includes the larynx,
trachea, bronchi, & lungs
Lower Respiratory Tract
a series of interconnecting cavities & tubes
Conducting zone
