VENTILATION/RESPIRATION: ANATOMY AND PHYSIOLOGY
1) Using Fick's law, explain why it is harder to breathe at thetop of Mount Everest.
2) Using Fick's law, justify why the body surface of aTurbellaria makes a good respiratory surface for the worm.
3) Recall the gills seen in your crayfish, squid, and clamdissections. Was that tissue usually described as \"feathery\" orwere they \"dense\" structures? From what you know of Fick's law, whydoes the characterization you use make sense?
4) What organisms have spiracles and why are they important forthat organism?
5) How is air moved through tracheae in insects?
6) Order the airway passages and/or structures that air goesthrough starting from the nose to the blood stream in humans. (Youshould have at least five passages)
B) what is the main differences between those passage ways?
7) Provide at least two ways the anatomy of the lung helps tomaximize Fick's law.
8) Describe how the diaphragm and muscles around the rib cagepromote negative pressure breathing.
B) What type of animals use positive-pressure breathing and whymight this be okay?
9) Describe at least two ways ventilation in birds is differentfrom ventilation in humans.
