- You receive animal care and use committee approval to catch a fish, prop open its operculum (gill cover), tie a string around its tail, and tow it backwards through the water for experimental purposes. The fish is then released unharmed. This action forces water to flow backwards over the gill filaments and in between the gill lamellae. What effect would this backwards water flow have on respiration? It would reduce efficiency of gas exchange between water and blood The only effect would be due to the fish's discomfort from this treatment. O It would improve efficiency of gas exchange between water and bloodDiscuss Tidal, residual, minimal air in Gaseous Exchange in AnimalsSharks and bony fishes approach or achieve neutral buoyancy in different ways. Describe the methods evolved in each group. Why must a teleost fish adjust the gas volume in its swim blad-der when it swims upward or downward? How is gas volume adjusted?
- 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?At various points throughout Earth’s geological history, atmospheric and oceanic oxygen levels have been different than they are today. If future oxygen levels in the ocean become higher than they are today, what effect do you think this will have on the relative frequencies with which ram ventilation or buccopharyngeal pumping are used by aquatic vertebrates? Please explain your answer.X Flow of the movement of gases during respiration in mammals
- Describe structural and functional differences between gills and lungs (ie. know the anatomy of lungs and gills). Why are birds’ lungs more efficient at removing O2 from the air compared with mammalian lungs?Regarding oxygen transport, deduce the specificadditional step that must occur in animals with a closedcirculatory system, compared to those with an open system.What are the different approaches taken by animals to solve the problems of external respiration? Differentiate each approach from one another by giving advantages and disadvantages of each one.
