Rate this question:
The trachea is anterior to the esophagus and divides at the carina
The right aspect of the bronchial tree is shorter and more vertical than the left
There are three lobes in the left lung and two lobes to the right lung
The interior surface of the alveoli is coated with surfactant which prevents atelectasis
Rate this question:
Lower altitudes
Supplemental oxygen
Aerobic metabolism
Room air
Rate this question:
Reserve volume is equal to the inspiratory reserve volume minus the expiratory reserve volume
The functional residual capacity is equal to expiratory reserve volume plus expiratory capacity
Total lung capacity is equal to the vital capacity plus the residual volume
Minute alveolar volume is equal to the produce of respiratory rate and tidal volume
Rate this question:
The phrenic and the intercostal nerves are the main afferent nerves
The pneumotaxic center is in the pons and is responsible for stimulating the inspiratory center
The primary involuntary respiratory center is located on the brain stem in the medulla
The apenustic center consists of the stretch receptors in the chest that serve to inhibit overinflation
Rate this question:
Arytenoid
Cuneiform
Corniculate
Cricoid
Rate this question:
Less oxygen bound to hemoglobin for a given PaO2
Hemoglobin has a greater affinity for oxygen for a given partial pressure of oxygen in blood
Carbon dioxide molecules displace oxygen molecules at a faster rate for a given SaO2
The oxygen dissociometer readings become increasingly inconsistent with end-tidal measurements
Rate this question:
The pediatric airway is narrower and jaw structures are smaller
The cricoid ring in the pediatric airway is smaller and the trachea is more rigid
The larynx is higher and more anterior in the pediatric airway, whereas the trachea is shorter and narrower
Clogging of the nose of very young children is potentially harmful since their tongues are larger and they are consequently obligate nose breathers
Rate this question:
Oropharynx - Laryngopharynx - Larynx - Hyoid Bone
Oropharynx - Nasopharynx - Larynx - Cricothyroid Membrane
Vallecula - Glottic Opening - Crycothyroid Membrane - Hyoid Bone
Oropharynx - Soft Palate - Hard Palate - Larynx
Rate this question:
Gas flows along a diffusion gradient from mixtures at low partial pressures to gaseous mixtures of high partial pressure
Oxygen and carbon dioxide is exchanged through the alveolar walls into the pulmonary capillaries via the interstitial space
Carbon dioxide best travels from the cells to the lungs dissolved as bicarbonate ions in the blood
Carbon monoxide poisoning is a form of dissociative shock that impairs gas exchange at the cellular level
Rate this question:
Rigidity of alveolar walls
Ease of ventillation
Softness of the trachea
Flexibility of the bronchioles
Rate this question:
Hypoxia
Hypocarbia
Anoxia

Rate this question:
Coughs, sneezes, sighs, and hiccoughs are all modified forms of ventillation
A cough is a violent, reflexive expulsion of gas through the nasal cavity that protects the upper airway
A hiccough is a spasm of the diaphragm
A sigh is a voluntary and periodic slow deep respiration followed by shortened exhalation
Rate this question:
Atmospheric pressure
Intrapleural pressure
Alveolar compliance
Intrapulmonic pressure
Rate this question:

Increased dead space
Altered chest compliance
Altered control of respiration
