ANATOMY AND PHYSIOLOGY
LECTURE EXAM 1 WITH 100%
CORRECT ANSWERS 2025/2026
Anatomy correct answers >> The branch of biology that
attempts to understand how things are structured internally and
externally
Physiology correct answers >> The branch of Biology that
attempts to understand how things work
Levels of physiological study correct answers >> body
system
orans
tissues
cells
organelles
ion channels
Homeostasis correct answers >> Maintaining the internal
state within narrow limits even during external change
How is homeostasis maintained? correct answers >>
Autoregulation or extrinsic regulation
, Autoregulation correct answers >> occurs when the activity
of a cell/tissue/organ adjusts automatically in response to
environmental change
Extrinsic regulation correct answers >> changes result from
the actions of the nervous or endocrine system
General regulatory mechanisms consist of: correct answers >>
Receptor, control center, and effector
Negative feedback correct answers >> Response shuts off or
migrates to original stimulus
Positive feedback correct answers >> Response exaggerates
original stimulus
Metabolism correct answers >> sum of all chemical reactions
in cells (catabolic + anabolic reactions)
Catabolic reactions correct answers >> "decomposition" -
snipping large into small
Anabolic Reactions correct answers >> "synthesis"- building
small into large
Inorganic Compounds correct answers >> Molecules that do
not contain carbon chains
