HPP LEC Chap 1 Flashcards
the scientific discipline that investigates the structure of the body
Anatomy
the study of the body by systems
Systemic Anatomy
the study of the organization of the body by areas
Regional Anatomy
the study of external features
Surface Anatomy
involves the use of x-ray, MRI, and other technologies to create pictures of internal features
Anatomical Imaging
the scientific discipline that deals with the processes or functions of living things
Physiology
studies the human organism
Human Physiology
involves how atoms interact and combine into molecules
Chemical Level
the basic unit of life
Cells
looks like compartments and has organelles that have specific functions
Cellular Level
group of similar cells and the materials surrounding them
Tissue Level
composed of two or more tissue types that together perform one or more common functions
Organ Level
a group of organs classified as a unit because of a common function
Organ System Level
any living thing considered as a whole
Organism Level
refers to the specific relationship of the many individual parts of an organism
Organization
the ability to use energy to perform vital functions
Metabolism
the ability of an organism to sense changes in the environment and make the adjustments that help maintain its life
Responsiveness
refers to an increase in size of all or part of the organism
Growth
includes the changes an organism undergoes through time
Development
change in cell structure and function from generalized to specialized
Differentiation
the existence and maintenance of a relatively constant environment within the body despite fluctuations in the environment
Homeostatis
measure of body properties that may change in value
Variables
normal or average value of a variable
Set point
maintain body temperature near an average normal value
Homeostatic mechanism
body temperature increases or decreases slightly around the set point
Normal range
the main mechanism used homeostatic regulation
Negative Feedback
deviation away from set point
Detection
reversal of deviation toward set point and normal range
Correction
monitors the value of variable
Receptor
determines the set point for the variable and receives input from the receptor
Control center
can change the value of the variable when directed by the control center
Effector
a changed variable that initiates homeostatic mechanism
Stimulus
