,homeostasis - CORRECT ANSWER-body's maintenance of a stable environment

receptors - CORRECT ANSWER-molecule or cell that provides information about the
environment

control center (and set point) - CORRECT ANSWER-indicates correct value (e.g. body
temp)

effectors - CORRECT ANSWER-What elicits a response that alters conditions within the
body's internal environment. (e.g. muscles and glands)

negative feedback - CORRECT ANSWER-When receptors measure deviations from the
set point, effectors are activated and conditions are returned toward the set point and
effectors gradually shut off. This movement toward homeostasis and balance is called
.........

positive feedback - CORRECT ANSWER-Homeostatic mechanisms that function when
changes byeffectors move the body away from normal conditions, causing more
changes, is called...... (examples are blood clotting and labor contractions)

pericardium and the parietal pericardium

middle ear cavities - CORRECT ANSWER-Cavity containing the incus, malleus, stapes

Pleural cavities (lungs) - CORRECT ANSWER-Cavities (right and left) that are the
potential space between the parietal and visceral pleural membranes

Abdominopelvic cavity - CORRECT ANSWER-Cavity that extends from the diaphragm
to the floor of the pelvis; includes stomach, liver, spleen, gallbladder, small and large
