Document Summary

Looking at individual nerves, the function in animals are similar to what we see in humans and other animals. Invertebrates have their skeleton on the outside called the exoskeleton. Fish are cold blooded, they adapt their body temperature to that of the environment: not always so: Marlin: have the ability to raise their internal temperature of their muscles and keep it 50-100 degrees higher than the rest of their body and the environment, core of muscles generate heat and trap heat. Looking at cardiovascular and respiratory systems between humans and animals you see a number of differences appearing: fish breathe using gills with the exception of fish that breathe air compared to water. The same muscles used to breathe (inflate their lungs) are are used to run. More blood vessels coming out of it than in a human. There are connections between different vessels that we don"t see in humans.
