PARADEMIC FISDAP AIRWAY EXAM WITH
CORRECT ACTUAL QUESTIONS AND
CORRECTLY WELL DEFINED ANSWERS
LATEST ALREADY GRADED A+
Bronchioles - ANSWERS-Made of smooth muscle & lined
with beta-2 receptors, which can dilate and constrict based
on stimuli.
Alveoli - ANSWERS-Balloon-like clusters of single-layer air
sacs, and serve as the functional site for the exchange of
oxygen and CO2. This exchange occurs by simple diffusion
over the pulmonary capillaries.
Ventilation - ANSWERS-Process of moving air in and out of
the lungs. Consist of two phases- inhalation and exhalation.
Oxygenation - ANSWERS-Process of loading O2 molecules
onto hemoglobin molecules in the bloodstream.
,Respiration - ANSWERS-Actual exchange of O2 and CO2 in
the alveoli and the tissues of the body.
Inhalation - ANSWERS-Air enters the body, the diaphragm
and intercostal muscles contract. When the diaphragm
contracts, it descends and enlarges the thoracic cage from
top to bottom. When the intercostal muscles contract, they
lift the ribs up and out.
Diaphragm - ANSWERS-Stimulated by the Phrenic Nerve, it
is a voluntary and involuntary muscle.
Accessory Muscles - ANSWERS-Secondary muscles of
breathing, and include the sternocleidomastoid and
trapezius muscles of the neck.
Negative Pressure Ventilation - ANSWERS-The air outside
the body, is normally higher in pressure than the air within
the thorax. During inhalation, the thoracic cage expands and
the air within the thorax decreases, creating a slight
vacuum. The vacuum pulls the air in through the trachea,
causing the lungs to fill.
, Positive Pressure Ventilation - ANSWERS-With ineffective
chest movement, or no chest movement, negative
intrathoracic pressure cannot be created. When this occurs,
the only way to move air into the lungs is by PPV, the forcing
of air into the lungs.
Tidal Vol/Dead Space/Residual Vol/Total Lung Capacity -
ANSWERS-Tidal- 500ml
Total Lung Capacity- 6,000ml/5-6L
Dead Space- 150ml
Residual Vol- 1,200ml
Hering- Breuer Reflex - ANSWERS-Terminates inhalation to
prevent over-expansion of the lungs.
Medulla - ANSWERS-Primary involuntary (autonomic)
respiratory center. Connected to the respiratory muscles by
the vagus nerve. The medullary respiratory center controls
the rate, depth, and rhythm of breathing.
Chemoreceptors - ANSWERS-Receptors that monitor the
chemical composition (pH, CO2,) of body fluids that are
located throughout the body. They measure the amount of
