Document Summary

At the collection sites to blood: gut, lungs/gills/skin. At the tissues: blood to tissues. Gut: vessels from the heart to the capillary bed are called arteries, vessels from the capillary bed to the heart are called veins, vessels from a capillary bed to another capillary bed are called portal veins. The nervous system: uses electrical signals, quick on/off, control internal operation internal movement, functions, etc, sensation, motion. The endocrine system: uses chemical signals, slower on/off. Unique animal tissues: nervous tissue, muscle tissue, both are required for coordinated movement, skeletons. Radiata vs bilateria: diffuse net vs ganglia, cephalization. Complexity and life style: the bigger the brain the more complex integration is, taking all information and putting it together into a big picture, the more active the animal, the bigger the brain. Voluntary control: taking information from all sensory receptors (sensory input) In the brain integration happens: brain and spinal cord (central nervous system)
