Textbook Question
Chapter 22, Problem 4TYK
Countercurrent gas exchange in the gills of a fish
a. maintains a gradient that enhances diffusion.
b. enables the fish to obtain oxygen without swimming.
c. means that blood and water flow at different rates.
d. allows O2 to diffuse against its partial pressure gradient.

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).
Define the term “exchange surface” and list four common features of gas-exchange organs in animals.
Describe some structural and functional features that are commonto all gas-exchange surfaces in animals.

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.
