Answers) (Solved) (260QS)
What is the purpose of the Scientific Method? - Test the hypothesis
What are the steps of the Scientific Method - 1. problem
2. hypothesis
3. procedure
4.analyze
5.conclusion
Independent Variable - The experimental factor that is manipulated; the variable whose effect is
being studied.
Dependent Variable - The outcome factor; the variable that may change in response to
manipulations of the independent variable.
Control Groups - groups whose members do not obtain the treatment, while other conditions are
held constant
Experimental Groups - treatment groups; the participants in a study that receive the intervention
Define Anatomy and Physiology - Anatomy: the study of the body's parts or the body's structure
Physiology: the sturdy of how the body parts work or how the body functions
Structure determines function; function determines structure - they're inseparable.
The six levels of organization - chemical, cellular, tissue, organ, organ system, organism
, Requirements of life - water, food, oxygen, heat, pressure
Survival needs - nutrients, oxygen, water, body temperature, atmospheric pressure
Homeostasis - A tendency to maintain a balanced or constant internal state; the regulation of any
aspect of body chemistry, such as blood glucose, around a particular level
Basic mechanism for homeostasis - receptor, control center, effector
Positive feedback loop - feedback loop that causes a system to change further in the same direction
Negative feedback loop - A feedback loop that causes a system to change in the opposite direction
from which it is moving
Anatomical Position - erect, feet forward, arms at side with palms facing forward, head facing
forward
Dorsal - toward the back
Lateral - away from the midline
Superior - above
Inferior - below
Anterior - toward the front
Posterior - toward the back
Medial - toward the midline
Distal - away from the point of attachment
