external membrane
protects your internal organs from drying out
integumentary system
includes all the activities pronoted by muscular system
movement
also occurs when substances are propelled through internal organs
movement
systems involved
muscular, skeletal, cardiovascular, digestive, urinary
irritability, ability to sense changes
responsiveness

force exerted on the surface of the body by the weight of air
atmospheric pressure
breathing and exchange of oxygen and carbon dioxy
atmospheric pressure
high altitude
the slower the gass exchange
ability to maintain equilibrium

control cebter
feedback
effector
efferent pathway
info flows
regulates heart rate
nega
rare in the body because they push ithe variable farther
positive feedback
blood clotting
positive
increasing the amount of change so the reaction continues at a faster rate
