intro to human anatomy and physiology Flashcards
investigates the body’s structure and the relationship between the body part and its function
anatomy
studied system by system, i.e.,
cardiovascular, nervous, skeletal, etc.
systemic anatomy
study of the external form of the body
and its relation to deeper structures
surface anatomy
uses radiographs (x-rays), ultrasound, magnetic resonance imaging (MRI), and other technologies to create pictures of internal structures
anatomical imaging
scientific investigation of the processes or functions
of living things
physiology
study of a specific organism
human physiology
examines processes in cells
cellular physiology
deals with organ system function
systemic physiology
this level of organization involves interactions between atoms that combine to form molecules, such as water, sugar, fats, and proteins
chemical level
this level of organization refers to the molecules combining to form organelles, small structures that make up cells
cell level
this level of organization is composed of a group of similar cells and this level is classified into four basic types: epithelial, connective, muscle, and nervous
tissue level
this level of organization is composed of two or more tissue types that perform one or more functions.
organ
this level of organization refers to the group of organs that perform a common function and are viewed as a unit
organ system
this level of organization refers to any living thing considered as a whole; it is a complex organ of organ systems, all mutually dependent on one another
organism
refers to the interrelationships among the parts of
an organism and how those parts interact to
perform specific functions
organization
the ability to use energy to perform vital function
metabolism
an organism’s ability to sense changes in its
external or internal environment and how it adjusts
to those changes
responsiveness
an increase in the number of cells, which produces
an overall enlargement of all or part of an organism
growth
includes the changes an organism undergoes
through time from fertilization to death
development
change in cell structure and function from generalized to specialized
differentiation
change in the shape of
tissues, organs, and the entire organism
morphogenesis
formation of new cells or new organisms
reproduction
regulates temperature
integumentary system
removes foreign substances from the blood and
lymph
lymphatic system
provides protection and support
skeletal system
performs chemical and mechanical digestion, absorption of nutrients, and elimination of waste
digestive system
produces body movements
muscular system
