Intro to Patho Flashcards
Disease
impairment of cell tissues, organ, or organ system functioning
Pathophysiology
study of the functional changes that occur in the body as a result of an injury, disorder, or disease
Pathogenesis
origination and development of illness or disease
Incidence
the rate at which it occurs (1 in 7 people smoke)
prevalence
number or percentage at a given time
Morbidity Rate
How many people have complications because of a disease
Mortality Rate
how many people have died because of the disease
Primary research
gives current research of what happening in patient population
Secondary data analysis
read a lot of info from different people
Meta Analysis
take a bunch of research and synthesize to find commonalities and put together
practice experience
understanding based on years of experience
Expert opinions
given experience, find x is the best way to do it
diffusion
solutes move from high concentration to low concentration- particles move seeking equilibrium
osmosis
diffusion of water molecules (water, not partciles, move to seek equilibrium)
Facilitated Diffusion
molecules diffuse across membrane by passing through a protien
Active Transport
requires energy- ATP moves particles in and out of the cell- ex is sodium potassium movement
Hydrostatic Pressure
force of blood on capillary walls- increased can move fluid across semi-permeable membrane. Moves from semi permeabl membrane to interstitial space-pushing pressure.
Endocytosis
process of transport large substances into cell
Pinocytosis
letting small subtances into the cell
Phagocytosis
large particles such as cells, bacteria, damaged cellular components taken into cell
Secretion
process of release of metabolic products from cells, cellular products packaged into vesicles and transported out by exocytosis
anabolism
producing energy
catabolism
energy release/use
cellular proliferation
increase in number of cells
