BIOL 1011 Lecture Notes - Lecture 1: Hydrostatic Skeleton, August Krogh, Hare
Document Summary
August krogh principle: for many problems there is an animal on which it can be most conveniently studied (comparative physiology) All medical advancements come from rats and mice. Strength (with growth comes a larger skeleton, larger muscles to a certain extent) Movement (most animals develop movement based on where they live, like water or in trees) ie. fish are very smooth and liner to move quickly through the water. Diffusion (with complex animals, they must develop a form which allows them to communicate with the environment for gases, nutrients and waste) *form gives clues to the function/physiology, they are related* Because they are full of capillaries, where they use them for heat exchange because their bodies are covered by fur. Want the highest surface area to volume ratio that you can for greater. Want the highest surface area to volume ratio that you can for greater exchange (ie. tubeworm) Each animal has different adaptations for exchange (gills, lungs etc)
