homeostasis Flashcards
surface anatomy
study of form and markings of the the body surface
gross anatomy
study of the anatomical structures visible to unaided eye
systemic approach
study of whole system
regional approach
study of specific region
histology
study of the microscopic structures of the tissue
cytology
study of the structure and function of cells
pathology
study of the causes and effects of diseases
cell
basic structural and functional units of an organism
tissues
groups of cells that work together to perform a similar function
4 basic types of tissues
epithelium, connective tissue, muscle, nervous tissue
organs
structures composed of two or more types of tissue
organ system
related organs with common functions
organism
collection of organ systems
6 important life processes
metabolism, responsiveness, movement, growth, differentiation, reproduction
metabolism
sums of all chemical reactions in the body
responsiveness
body’s ability to detect and respond to changes
movement
any motion
growth
increase in body size
differentiation
development of a cell from an unspecialized to specialized state
reproduction
formation of new cells or new individual
three basic components of homeostasis
receptor, control center, effector
receptor
body structure that monitors changes in a controlled condition and send input
control center
sets the range of values to be maintained: generates output
effector
receives output from the control center and produces a response
