Lab 3 Flashcards
What is the process of maintaining steady internal temperature and what systems are involved
Thermoregulation
Nervous, circulatory, muscular, integumentary
Human urinary system
When you drink too little
Brian sends signals to nervous system to increase ADH in blood and signals kidneys to re absorb water back into body making urine more concentrated
Diuretics do what
Inhibit release of ADH resulting in excessive urinary water loss
Negative feedback
Result of a process that inhibits the same process
Positive feedback
Result of process intensifies same process
Inhibitory neurotransmitters v excitatory
Block nerve impulses
Amplify nerve impulses
Stimulants
Enhancing excitatory
Or blocking inhibitory
Depressants
Block the action of a excitatory
Enhance action of an inhibitory
Controlled experiment
Methods of science where an experimental and control test are carried out in parallel
The experimental differs from the control in what factor
Variable being tested
If the experimental differs from the control by more than one factor they are considered
Confounding variables
Why should multiple replicated be conducted
In order to estimate variability of responses
If we have not assessed variation then the experiment is not
Complete , just an anecdote and can’t make conclusions or inferences
