Gas Exchange Surfaces in Animals
Students will examine the diverse adaptations for gas exchange in animals, including gills, lungs, and tracheal systems, relating structure to function.
Key Questions
- Compare the structural features of gills, lungs, and tracheal systems that maximize gas exchange efficiency.
- Explain how the principles of diffusion apply to gas exchange across respiratory surfaces, considering surface area, thickness, and concentration gradients.
- Analyze the evolutionary pressures that led to different gas exchange strategies in various animal phyla and environments.
