	B: bronchioles
	C: bronchi
	D: none of the above

4: Which of the following is not true?
	A: Alveolar macrophages or dust cells are phagocytic cells that remove particles from the lungs
	B: Dust cells produce surfactant a chemical that reduces surface tension in the alveoli and helps keep them from collapsing
	C: Mucous cells lining the conducting portion of the respiratory system produce mucus which traps dust particles
	D: Cilia on cells lining much of the conducting portion of the respiratory system help keep the lungs clear of dust and bacteria

5: The olfactory membrane
	A: is a patch of cells that is responsible for the sense of taste
	B: contains receptors cells that perceive smell
	C: is located in the roof of the oral cavity
	D: is the site of the vocal cords

	A: rhinitis
	B: sinusitis
	C: bronchitis
	D: laryngitis

7: Cigarette smoke
	A: reduces the production of mucus in the respiratory tract
	B: contains particles of carbon that are rapidly cleansed from the lungs
	C: contains sulfur dioxide, which temporarily paralyzes the cilia in the lungs
	D: contains pollutants that increase the lungs' natural cleansing mechanism

8: In the lungs, oxygen
	A: travels from the blood, through the wall of the alveolus, then into the alveoli
	B: travels from alveolar air through the wall of the alveolus into surrounding capillaries
	C: travels from areas of high to low concentrations via diffusion
	D: a and b
	E: b and c

9: Most oxygen in the blood is
	A: transported in the plasma as bicarbonate ions
	B: transported in the plasma bound to hemoglobin molecules
	C: is transported inside the red blood cells bound to hemoglobin molecules
	D: none of the above

10: The large muscle separating the abdominal and thoracic cavities
	A: is known as the diaphragm and is under involuntary control
	B: is the intercostal muscle and is involved in inhalation
	C: flattens and lowers when it contracts, forcing air out of the lungs

	E: none of the above

11: During inspiration, the rib cage
	A: lifts up and out
	B: does not move
	C: compresses
	D: none of the above

12: Which of the following is true?
	A: Inhalation is a passive process
	B: Intrapulmonary pressure increases as the diaphragm falls
	C: The air that moves in and out of the lungs with each breath is called the residual volume
	D: Exhalation is generally a passive process, involving relaxation of the muscles the chest wall and the diaphragm

13: Breathing is controlled by the breathing center located in the
	A: cerebral cortex
	B: brain stem
	C: sinoatrial node
	D: lungs

14: The most important chemical in the control of breathing is
	A: oxygen
	B: hydrogen
	C: carbonic acid
	D: carbon dioxide

15: Asthma is
	A: typically caused by an allergic reaction to common substances such as pollen
	B: characterized by periodic episodes of wheezing and difficulty breathing
	C: characterized by a constriction of the bronchioles in the lungs
	D: a and c
