The respiratory system of which of the following organisms relies on air sacs to
move air through the lungs? A. birds B. mammals C. fish D. amphibians E.
reptiles
A. Birds
Which of the following statements is true regarding respiration in mammals?
Select all that apply. A. Air moves in a unidirectional fashion through the lungs.
B. Gas exchange occurs in the bronchioles. C. Gas exchange occurs in the
alveoli. D. Respiration depends on changes in air pressure in the chest cavity. E.
Respiration depends on contractions of the diaphragm.
C. Gas exchange occurs in the alveoli. D. Respiration depends on changes in air
pressure in the chest cavity. E. Respiration depends on contractions of the diaphragm.
Simple multicellular organisms that are small can meet their gas exchange needs
by means of: Select all that apply. A. a flattened body shape that increases
surface area B. a flattened or thin body shape that reduces the distance between
cells inside their body and the external environment C. by living in air that
provides abundant oxygen, even though they are at risk of losing water and
drying out D. by living in water so that they do not dry out from water loss, even
though water has less oxygen per volume than air E. by relying on anaerobic
respiration (glycolysis) for long time periods, so that they don't need to use
oxygen for aerobic respiration
A. a flattened body shape that increases surface area B. a flattened or thin body shape
that reduces the distance between cells inside their body and the external environment
D. by living in water so that they do not dry out from water loss, even though water has
less oxygen per volume than air
Imagine that a young girl suffers a horseback-riding injury, and one of her ribs
punctures her diaphragm. How will this injury affect the girl's breathing? A. The
injury will make it easier to increase negative air pressure in her chest cavity,
making inhalation easier. B. The injury will make it more difficult to increase
negative air pressure in her chest cavity, making inhalation more difficult. C. The
injury will make it more difficult to decrease negative air pressure in her chest
cavity, making inhalation more difficult. D. The injury will not affect her at all, as
intercostal muscles are responsible for breathing.
B. The injury will make it more difficult to increase negative air pressure in her chest
cavity, making inhalation more difficult
Which of the following present challenges that make gas exchange more difficult
for fish than for terrestrial animals? Select all that apply. A. Water is denser and
more viscous than air. B. Water contains much less O2 than air per unit volume.
C. Gills have less surface area than lungs. D. Unidirectional flow of water is less
efficient than tidal ventilation. E. Diffusion occurs more slowly in water than in air.
A. Water is denser and more viscous than air. B. Water contains much less O2 than air
per unit volume. E. Diffusion occurs more slowly in water than in air.
