ENDOCRINOLOGY & METABOLISM RESOURCES

The coordinated
physiological
processes which
maintain most of the
steady states in the
organism are so
complex and so
peculiar to living
things--involving as
they may, the brain
and nerves, the
heart, lungs,
kidneys, and spleen,
all working
cooperatively--that I
have suggested a
special designation
for these states,
homeostasis. The
word does not imply
something set and
immobile, a
stagnation. It means
a condition--a
condition which may
vary, but which is
relatively constant.
