primary function is to contract or shorten to allow for locomotion, grasping, and manipulation of the environment & facial expression
muscular system
generates heat
muscular system
allows body to detect changes in its internal and external environment and to respond to such information by activating appropriate muscles or glads
nervous system
helps maintain homeostasis of the body via rapid transmission of electrical signals
nervous system
helps maintain body homeostasis, promotes growth and development, produces chemical messengers called hormones that travel in the blood to exert their effects on various target organs of the body

digestive system
undigested residue is removed from the body as feces
digestive system
rids the body of nitrogen-containing wastes including urea, uric acid, and ammonia, which result from the breakdown of proteins and nucleic acids
