Chemical and physical properties of gases are important factors in the evolution and physiology of cardiorespiratory systems. Which of the following statements about gases and cardiorespiratory systems is FALSE? When a frog sits in anoxic water, they can get enough oxygen by breathing air. Under these conditions, it makes sense to reduce the blood flow through the skin to reduce loss of oxygen from the blood to the water. When ancient fish began breathing air, they discovered that air was respiratory fluid that was richer in oxygen than was the water they breathed when submerged. When humans climb to high altitude, they breath more frequently to obtain sufficient oxygen and in doing so, get rid of too much carbon dioxide, causing an alkalosis (increase in blood pH). Because the ratio of oxygen to carbon dioxide is higher air than water, air breathing is linked to getting enough oxygen whereas water breathing is regulated to get rid of carbon dioxide.

EVOLUTION LINK Aquatic mammals such as whales and dolphins use lungs rather than gills for gas exchange. Propose a hypothesis to explain why.
Can you answer all the parts to this question regarding fish (please type the answer) Mammals have dead end sacs called “alveoli” and don’t have the super efficient countercurrent exchange system seen in fish. Why do you think countercurrent exchange is necessary for fish? (hint: think about the difference between where most mammals and fish live).
When researchers first discovered that airflow through a bird’s paleopulmonal parabronchi is unidirectional, the question arose as to whether gas exchange is countercurrent, cocurrent, or cross- current. Some ingenious investigators carried out experiments in which they measured the efficiency of gas exchange between air and blood in duck lungs when parabronchial airflow was in its normal direction and when the direction of parabronchial airflow was artificially reversed. The efficiency did not change. How is this evidence against countercurrent and cocurrent gas exchange? How is this evidence for cross-current exchange?
Which of the following respiratory systems is not closely associated with a blood supply? O the lungs of a vertebrate the gills of a fish the tracheal system of an insect the skin of an earthworm
In amphibians, cutaneous gas exchange is particularly important, especially in some species of lungless salamanders. Draw the circulation of oxygen-rich and oxygen-poor blood during cutaneous gas exchange for a lungless salamander. Upload your image (may be hand drawn or digitally rendered).
Can you answer all the parts to this question regarding fish A: Describe countercurrent exchange in your own words. B: Describe concurrent exchange in your own words. C: Mammals have dead end sacs called “alveoli” and don’t have the super efficient countercurrent exchange system seen in fish. Why do you think countercurrent exchange is necessary for fish? (hint: think about the difference between where most mammals and fish live).
Which of the following provides the best evidence that the circulatory system and the respiratory system work together to carry out their functions?
The amount of time that scuba divers can spend underwater is lim-ited by several factors, including time required to deplete the air sup-ply in their tanks. To make their air last longer, novice divers may be instructed to breathe slowly and exhale as much as possible on each breath. Can you suggest a reason why this behavior would lengthen a diver’s air supply?

If water passed over the gills of fish in the same direction as blood flow through the capillaries, how would gas exchange be affected? Select all correct choices. More oxygen would diffuse from the water into the fish's bloodstream. Less oxygen would diffuse from the water into the fish's bloodstream. More carbon dioxide would diffuse out of the fish's bloodstream into the water. Less carbon dioxide would diffuse out of the fish's bloodstream into the water. Gas exchange would remain the same, regardless of the direction of water flow.
Which one of the following statements about the afferent components of the respiratory control system is INCORRECT? Select one: a. In order to stimulate hyperventilation the sympathetic nervous system tricks the carotid body by constricting the capillaries that serve glomus cells; reduced blood flow to the cell causes localised hypoxia triggering a compensatory hyperventilation response even before systemic hypoxia is apparent. b. In type 1 glomus cells of the carotid bodies, hypoxia, hypercapnia and acidosis trigger afferent signalling by inhibiting K+ channels, depolarising the cell membrane, and opening voltage-gated Ca2+ channels that trigger the release of neurotransmitters onto afferent glossopharyngeal nerve fibres. c. Chemoreceptor cells can be found in the carotid body. d. The glossopharyngeal nerve transmits afferent impulses from the carotid body to the ventral respiratory group of neurons.
