Already Passed Answers.
Which statement is true regarding the pulmonary system? - Answer The larynx connects the upper and
lower airways
Which statement is true regarding the lower airways? - Answer The right and left main bronchi enter
the lungs at the hila.
What process describes the exchange of carbon dioxide (CO2) for oxygen? - Answer Respiration
Which receptor monitors the pH, partial pressure of CO2 (PaCO2), and the partial pressure of oxygen
(PaO2) in arterial blood? - Answer Central chemoreceptors
Which physiologic alteration is present in an individual with emphysema? - Answer Increased
compliance
Which steps are involved in the process of gas exchange? (Select all that apply.) - Answer Ventilation,
Diffusion, Perfusion
Which structures are considered part of the upper airway? (Select all that apply.) - Answer
Nasopharynx, Oropharynx
Which structures are considered part of the acinus? (Select all that apply.) - Answer Respiratory
bronchioles, Alveolar ducts, Alveoli
Which structures are major accessory muscles of respiration? (Select all that apply.) - Answer
Diaphragm, External Intercostals
Which alterations involved with aging are considered normal? (Select all that apply.) - Answer

, The binding of oxygen to hemoglobin occurs in the lungs; the reverse process in which oxygen is released
from hemoglobin occurs in the? - Answer Tissues
The mechanical movement of gas or air into and out of the lungs is known as ventilation. Breathing is
usually involuntary because changes in the rate and volume are adjusted automatically by the nervous
system to maintain normal gas exchange. The respiratory system in the brain that becomes active when
increased ventilatory effort is required is the? - Answer Dorsal respiratory group
Which illness is a type of liquefactive necrosis? - Answer Abscess
Which statement is true regarding bronchiolitis? - Answer Respiratory distress develops within 24-72
hours
What is the appropriate term for inadequate alveolar ventilation in relation to metabolic demands? -
Answer Hypoventilation
A person has respirations that are characterized by alternating periods of deep and shallow breathing
and apnea. What is the appropriate term for this breathing? - Answer Cheyne-Stokes
Which is the most common cause of pulmonary edema? - Answer Heart disease
What is the term used to describe a respiratory infection that results in pus in the pleural space? -
Answer Emphyema
Which statement is true regarding acute respiratory distress syndrome (ARDS)? - Answer ARDS can
trigger severe pulmonary edema
Which statement is true regarding the pathophysiologic process of asthma? - Answer Inflammation
results in airway hyperresponsiveness
Inflammation results in airway hyperresponsiveness - Answer Air droplet
