12. All living things have certain
characteristics that distinguish them from
nonliving things
Life processes in humans include

13. An autopsy is a postmortem examination
of the body and dissection of its internal
organs to confirm or determine cause of
death

14. Homeostasis is a condition of equilibrium,
or balance, in the body’s internal
environment
Homeostasis is maintained by regulatory
processes

15. The survival of our body cells is
dependent on the precise regulation of the
chemical composition of their surrounding
fluid
This fluid is known as extracellular fluid

22. Anatomical position is a standardized
method of observing or imaging the body
that allows precise and consistent
anatomical reference
Person stands erect, facing the observer,
the upper extremities are places at the
sides, the palms of the hands are turned
forward, and the feet are flat on the floor
