Chapter 1 HAPLEC Flashcards
Study of structure and function of the human body
Human anatomy and physiology
Scientific discipline that investigates the structure of the body
Anatomy
Study of body systems ( cardiovascular, nervous, skeletal)
Systemic anatomy
Study of organization of the body by areas
Regional anatomy
General way to examine internal structures that studies the external features
Surface Anatomy
Gen ways to examine internal structures that involves the use of xray ultrasound magnetic resonance imaging MRI
Anatomical imaging
Study of nature; scientific discipline that deals with the process or functions of living things
Physiology
Major goals of physiology
To understand and predict the bodys response to stimuli; to understand how the nody maintains conditions within a narrow range of values
Study of specific organism
Human physiology
STRUCTURAL AND FUNCTIONAL ORGANIZATION OF THE HUMAN BODY
Chemical level; cell level; tissue level; organ level; organ system level; organism level
Involves how atoms interacts and combine into molecules
Chemical level
Basic structural snd functional units of organisms
Cell
Small structures that make up cells
Organelles
A molecule cells use for a source of energy
ATP
Group of similar cells
Tissue
Compose of two or more tissue tyoed to perform one or more common functions
Organ
Grp of orgams classifies as a unit
Organ system
Living thing considered as a whole
Organism
CHARACTERISTICS OF LIFE
Organization, metabolism, responsiveness,growth,development, reproduction /// differentiation?
Charac.of life// specificnterrelationships among the parts of an organisms and how those parts interact
Organization
Ability to use energy to perform vital functions. Duch as growth, movement and repro.
Metabolism
Ability of an organism to semse changes in the environment
Responsiveness
Refers to an increase of size of all or part of the organism
Growtj
Changes in organism undergoes through time; begins with fertilization and ends to death
Development
Change in cell structure and function from generalized to specialized
Differentiation
Doemation of new cells or new organisms
Reproduction
Conditin which body functions, body fluids , and other factors of the internal environment are maintained w/in a range of values suitable to support life
Homeostatis
Maintains homeostatis;
Negative feedback
3 receptors of negative feedback
Receptor- monitors the value of a variable
Control center - establishes set point around variable
Effector- changes the value of the variable
initiates a homeostatic mechanism
Stimulus
Occurs when the initial stimulus further syimulates the response; make deviations from normal even greater
Positive feedback mechanism
