nervous system function

-fast-acting control system of the body

-responds to internal and external changes by activating appropriate muscles and glands

nervous system major organs

endocrine system function

-glands secrete hormones that regulate processes (growth, reproduction, and nutrient use by body cells)

cardiovascular system function

-blood vessels transport blood

-heart pumps blood

lymphatic system functions

-picks up fluid leaked from blood vessels and returns it to blood

-disposes of debris in the lymphatic stream
