You receive animal care and use committee approval to catch a fish, prop open itsoperculum (gill cover), tie a string around its tail, and tow it backwards through thewater for experimental purposes. The fish is then released unharmed. This actionforces water to flow backwards over the gill filaments and in between the gilllamellae.

EVOLUTION LINK Aquatic mammals such as whales and dolphins use lungs rather than gills for gas exchange. Propose a hypothesis to explain why.
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?
Describe some structural and functional features that are commonto all gas-exchange surfaces in animals.

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?
Explain some structural and functional features that are common to all gas-exchange surfaces in animals.
Compare the two types of gas exchange systems in invertebrates. Based on your observation of the tracheal system of an aquatic insect: mosquito wriggler) & book lung systems (in invertebrates: spider (Araneae), explain how these systems are similar and how they differ from one another. (i.e. structures involved & relation to circulatory system). In cockroach, do the spiracles occur in pairs? What do you think happens if you block oxygen from coming into the body and prevent carbon dioxide from leaving?
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).

All human systems have the concept involving the flow of a molecule through system structures. (a) Using a flowchart (word, with > symbols), illustrate the path of air during exhalation. (b) Describe the muscular action of the diaphragm during exhalation. I forgot explain and tell me why
Which of the following mechanisms is not likely to be useful for ventilation in air? A) Ram ventilation B) A and B are not useful C) External medium movement D) None of the choices is useful E) Cilia
As a scuba diver descends, the pressure of the water on the bodyprevents normal expansion of the lungs. To compensate, the diverbreathes pressurized air, which has a greater pressure than air at sealevel. What effect does the increased pressure have on the amount ofgas dissolved in the diver’s body fluids? A scuba diver who suddenlyascends to the surface from a great depth can develop decompressionsickness (the bends), in which bubbles of nitrogen gas form. Theexpanding bubbles damage tissues or block blood flow through smallblood vessels. Explain why the bubbles develop.
