BIOL 2213 EXAM 1 WITH COMPLETE SOLUTIONS
homeostasis ANSWER the state of dynamic constancy in internal environment
set point ANSWER the value for which a variable operates optimally
dynamic constancy ANSWER correction in opposite direction of deviation back to set
point
negative feedback loop ANSWER feedback loop that causes a system to change in the
opposite direction from which it is moving
negative feedback loop pathway ANSWER sensors, integrating center, effector
positive feedback loop ANSWER a feedback loop that amplifies change in a system
positive feedback loop pathway ANSWER stimulus, cellular responses magnify
deviation, deviation leads to more cellular response, end product
intrinsic regulation ANSWER cells within an organ detect a change and send a signal to
nearby cells to respond
extrinsic regulation ANSWER the brain or other organs regulate an organ via the
endocrine or nervous system
mechanical force - ANSWER muscle cells and tissues generate
skeletal, smooth, cardiac - ANSWER 3 types of muscle tissue
, neuron - ANSWER ________ conduct electrical signals to other cells
central nervous system - ANSWER neurons & nervous tissue make up the
epithelial cells and tissue - ANSWER linings and covering of organs and cavities
secretion, absorption, protection - ANSWER epithelial tissue is specialized for
connective tissue - ANSWER connects, anchors, and supports structures in body
connective tissue; includes bone, cartilage and blood
body fluids solution of water with dissolved oxygen, nutrients, and waste
65 intracellular fluid makes up ___% of all body fluid
plasma and interstitial fluid 2 extracellular fluids
muscle, nervous, epithelial, connective the 4 primary tissues are
change in cells the binding of molecules to receptors causes
transporting, communicating, and affecting overall functions of organs - ANSWER the
binding of molecules to receptors serves in
hormones, enzymes, neurotransmitters, gases - ANSWER examples of molecules
binding
