ANAPHY MIDTERMS 1 Flashcards
consists of the structures
used to acquire O2 and remove CO2 from the
blood.
respiratory system
is a by-product of ATP production and must
be removed from the blood.
CO2/Carbon Dioxide
Increased levels of CO2 will _____ the pH of the
blood
lower
breathing, the movement of air into
and out of the lungs
Ventilation
the exchange of O2 and
CO2 between the air in the lungs and the blood
External Respiration
O2 and CO2 travel in the blood
to and from cells
Gas Transport
the exchange of O2 and
CO2 between the blood and the tissues
Internal Respiration
The lungs
produce an enzyme called ________ which regulates blood pressure.
angiotensin-converting
enzyme (ACE)
Air moving past the vocal
folds makes sound and speech possible.
Voice production
The sensation of smell occurs when
airborne molecules are drawn into the nasal cavity
Olfaction
The respiratory system provides
protection against some microorganisms by
preventing them from entering the body and
removing them from respiratory surfaces.
Protection
encloses the chamber for air
inspiration.
External nose
a cleaning, warming, and
humidifying chamber for inspired air.
Nasal cavity
commonly called the throat, it serves
as a shared passageway for food and air.
Pharynx
the voice box
Larynx
structures from the
nose to the larynx
Upper respiratory tract
structures from the
trachea through the alveoli in the lungs
Lower respiratory tract
structures from the nose to
the air tubes within the lungs used strictly for
ventilation
Conducting zone
small air tubes in the lungs
and the alveoli where gas exchange occurs
Respiratory zone
composed of mainly of hyaline cartilage
External nose
extends from nares (nostrils) to the choana which
are the openings to pharynx
Nasal cavity
air filled spaces within bone
Paranasal sinuses
bony projections on each side of nasal cavity, help in cleaning, humidifying, warming of air
Conchae
a common passageway for the respiratory
and digestive systems
PHARYNX
takes in air
Nasopharynx
extends from uvula to epiglottis, takes in food,
drink, and air
Oropharynx
extends from epiglottis to esophagus,
food and drink pass through
Laryngopharynx
