Anatomy - answer the study of the structure of body parts, it is a science and can be
examined or felt, observed or disected
Physiology - answer the study of the function of body parts, how do they work? what do
they do?
Atom - answerthe least complex level, the smallest particle of an element
Molecule - answerparticle made of 2 or more atoms
Macromolecule - answerinside cells, small molecules, ex: lipids, proteins, and nucleic
acids
Organelle - answersmall organs of a cell each with a particular function, laborers of the
cell, ex: mitochondria
Cell - answerthe basic unit of structure and function of living things, they vary in size
and shape, and function
Tissue - answergroups of cells functioning together
Organ - answerstructure made of a group of tissues
Organ System - answergroups of organs functioning closely together
Human Organism - answerthe most complex level of organization made of organ
systems
Characteristics of Life - answermovement, responsiveness, growth, reproduction,
respiration, digestion, absorption, circulation, assimilation, and excretion
Maintenance of Life (Requirements of Organisms) - answerwater, food, oxygen, heat,
and pressure
Homeostasis - answerthe tendency of an organism to maintain a stable internal
enviroment
Negative Feedback - answerResponses move in opposite directions, reduces amount of
change. Brings conditions back to the set point
Positive Feedback - answerConditions are purposely moved away from the set point
, Receptor - answersense change in the enviroment

Retroperitoneal - answerWhen the kidneys, adrenal glands, pancreas, and ureters are
behind the abdominopelvic cavity
Serous Membrane - answera soft, thin, pliable layer of tissue that either covers a vital or
