framework the muscles use to support movement. Made up of bones and joints
reproductive system - ANSWER-Reproduce offspring- produce male sex cells
(sperm) and female sex cells (oocytes)
Muscular System - ANSWER-Allows manipulation of the environment, locomotion,
and facial expression. Maintains posture, and produces heat.
endocrine system - ANSWER-the body's "slow" chemical communication system; a
set of glands that secrete hormones into the bloodstream

organs. Provides defense against infection.
positive feedback mechanisms - ANSWER-Feedback that tends to cause the level of
a variable to change in the same direction as an initial change
negative feedback mechanisms - ANSWER-the net effect of the response to the
