Anatomy - (ANSWER)Study of structure of an organism and the relationship of its parts. Types of
anatomy: gross anatomy, microscopic, developmental, pathological, systemic
Physiology - (ANSWER)science that deals with the functions of the living organism and its parts. How the
body works
Characteristics of life - (ANSWER)Responsiveness, conductivity, Growth, Respiration, Digestion,
Absorption, Secretion, Excretion, Circulation, Reproduction
Responsiveness - (ANSWER)Ability of an organism to sense, monitor and respond to changes in both its
internal and external environments
Conductivity - (ANSWER)Capacity of living cells to transmit a wave of electrical disturbance from one
point to another within the body
Growth - (ANSWER)Organized increase in the size and number of cells and therefore an increase in size
of the individual or a particular organ or part
Respiration - (ANSWER)Exchange of respiratory gases (oxygen and carbon dioxide) between an organism
and its environment
Digestion - (ANSWER)process by which complex food products are broken down into simpler substances
that can be absorbed and used by individual body cells
Absorption - (ANSWER)movement of molecules, such as respiratory gases or digested nutrients, through
a membrane and into the body fluids for transport to cells for use

Secretion - (ANSWER)production and release of important substances, such as digestive juices and
hormones, for diverse body functions
Excretion - (ANSWER)removal of waste products from the body
Circulation - (ANSWER)movement of body fluids containing many substances from one body area to
another in a continuous, circular route through hollow vessels
Reproduction - (ANSWER)formation of new individual offspring
autopoiesis - (ANSWER)living organisms are self-organizing or self-maintaining and nonliving structures
are not.
cell theory - (ANSWER)any independent structure made up of one or more microscopic units called cells
is a living organism
metabolism - (ANSWER)each characteristic of life is related to the sum total of all the physical and
chemical reactions occurring in the body
levels of organization - (ANSWER)atom--molecule--macromolecules--organelle--cell--tissue--organ--
organ system--organism
atom - (ANSWER)tiny spheres of matter, every material thing in the universe, including the human body
is composed of atoms. Combinations of atoms form larger chemical groupings
molecules - (ANSWER)combos of atoms that form larger chemical groupings

macromolecules - (ANSWER)molecules in combination with other atoms form these larger and more
complex chemicals
cytoplasm - (ANSWER)atoms, molecules and macromolecules in living material form this gel like material
made of fluids, particles and membranes--the essential material of human life
organelles - (ANSWER)a structure made of molecules organized in such a way that it can perform a
specific function. Tiny organs that all each cell to live. Cannot survive outside the cell, but without
organelles the cell could not survive.
Types of organelles - (ANSWER)Mitochondria-power house of cells that provide energy needed by the
cell to carry out day-to-day functioning, growth and repair.
Golgi apparatus-set of sacs that provide "packaging" service to cells by storing material for future
internal use or for export from the cell
Endoplasmic Reticulum--network of channels within the cell that act as "highways" for the movement of
chemicals and as sites for chemical processing
cellular level - (ANSWER)cells are the smallest and most numerous structural units that possess and
exhibit the basic characteristics of living matter. Each cell is surrounded by a membrane and a single
nucleus surrounded by cytoplasm that includes the numerous organelles required for the normal
processes of living
tissue level - (ANSWER)a group of a great many similar cells that all developed together from the same
part of the embryo and all perform a certain function. Tissue cells are surrounded by varying amounts
and kinds of nonliving intercellular substances, or the matrix
Four major principal tissue types - (ANSWER)epithelial, connective, muscle and nervous
