Ch. 1 Study Guide (incomplete) Flashcards
anatomy
study of structure
chemistry
study of chem rxns between atoms and molecules
positive feedback
output enhances original effect of stimulus
ex: pregnancy/labor
anabolism
chem rxns that make smaller substances into bigger substances; require energy
physiology
study of body fxns
negative feedback
output reduces original effect of stimulus
catabolism
chem rxns that breakdown molecules/substances into smaller substances; release energy
histology
study of tissues
homeostasis
maintain equilibrium
metabolism
converts food into energy
complimentarity
a complimentary relationship
survival needs of living things
maintain boundaries; movement; responsiveness; digestion; metabolism; disposing if waste; reproduction; growth
survival needs: maintaining boundaries
ex: plasma membranes, skin
survival needs: movement
of body parts and substances throughout the body
survival needs: responsiveness
ability to sense and respond to stimuli; reflexes, breathing rate
survival needs: digestion
breakdown of ingested foodstuffs; absorption into blood
survival needs: metabolism
all chem rxns in body; catabolism and anabolism
survival needs: disposal of waste
excretion of wastes from metabolism (cells) and digestion
survival needs: reproduction
cell division for growth and repair; produce offspring
survival needs: growth
increase in size of a body part or of an organism
IDENTIFY SPECIFIC EXAMPLES OF HOMEOSTASIS AND NEGATIVE FEEDBACK REGULATION
blood, glucose, calcium, and BP
atom
smallest unit of matter that makes up an element
element
anything that cant be broken down into a smaller substance and still retain its unique chem properties
cell
structural and fxnal unit of life
