What keeps the visceral and parietal pleural membranes in contact with each other?
Where are alveoli found
in the lungs
Premature babies commonly suffer from infant respiratory distress syndrome (IRDS), which results from lack of alveolar surfactant. What does this surfactant prevent that is the problem in IRDS?
What term describes the movement of air into and out of the lungs
What is the role of bicarbonate ion in gas transport?
transports most of the carbon dioxide
Which of these events will occur with voluntary breath-holding?
Increases in carbon dioxide and H+ will override voluntary control and breathing will resume.
Which term describes the volume of air that CANNOT be exhaled?
What conditions is NOT characteristic of emphysema?
What is NOT a physical factor that influences the respiratory rate?
amount of O2 and CO2 in the blood
What term is used for the movement of oxygen into the blood of pulmonary capillaries and carbon dioxide into the alveolar air?
Which muscles contract to decrease thoracic volume and raise intrapulmonary pressure?
internal intercostal muscles
By what process does oxygen move from the alveoli into the blood of the pulmonary capillaries?
the diaphragm and rib muscles contract.
From which structures do oxygen molecules move from the lungs to the blood?
After blood becomes oxygenated,
it returns to the heart, and is then pumped to body cells.
is a protein that can bind four molecules of oxygen.
what is the pressure during inhalation
lower than the atmospheric pressure
Which of the following statements describe the normal changes that occur in respiratory system functioning from infancy to old age?
Many old people tend to become hypoxic during sleep and exhibit sleep apnea.
Premature infants have problems keeping their lungs inflated because of lack of surfactant in their alveoli
What is the main stimulus for increasing pulmonary ventilation during aerobic exercise?
increased concentration of carbon dioxide in blood
By which of these are tiny dust particles removed from alveolar surfaces?
How is most carbon dioxide transported from body cells to the lungs?
As bicarbonate ions
