Intro to Patho

Question 1

Disease

Answer 1

impairment of cell tissues, organ, or organ system functioning

Question 2

Pathophysiology

Answer 2

study of the functional changes that occur in the body as a result of an injury, disorder, or disease

Question 3

Pathogenesis

Answer 3

origination and development of illness or disease

Question 4

Incidence

Answer 4

the rate at which it occurs (1 in 7 people smoke)

Question 5

prevalence

Answer 5

number or percentage at a given time

Question 6

Morbidity Rate

Answer 6

How many people have complications because of a disease

Question 7

Mortality Rate

Answer 7

how many people have died because of the disease

Question 8

Primary research

Answer 8

gives current research of what happening in patient population

Question 9

Secondary data analysis

Answer 9

read a lot of info from different people

Question 10

Meta Analysis

Answer 10

take a bunch of research and synthesize to find commonalities and put together

Question 11

practice experience

Answer 11

understanding based on years of experience

Question 12

Expert opinions

Answer 12

given experience, find x is the best way to do it

Question 13

diffusion

Answer 13

solutes move from high concentration to low concentration- particles move seeking equilibrium

Question 14

osmosis

Answer 14

diffusion of water molecules (water, not partciles, move to seek equilibrium)

Question 15

Facilitated Diffusion

Answer 15

molecules diffuse across membrane by passing through a protien

Question 16

Active Transport

Answer 16

requires energy- ATP moves particles in and out of the cell- ex is sodium potassium movement

Question 17

Hydrostatic Pressure

Answer 17

force of blood on capillary walls- increased can move fluid across semi-permeable membrane. Moves from semi permeabl membrane to interstitial space-pushing pressure.

Question 18

Endocytosis

Answer 18

process of transport large substances into cell

Question 19

Pinocytosis

Answer 19

letting small subtances into the cell

Question 20

Phagocytosis

Answer 20

large particles such as cells, bacteria, damaged cellular components taken into cell

Question 21

Secretion

Answer 21

process of release of metabolic products from cells, cellular products packaged into vesicles and transported out by exocytosis

Question 22

anabolism

Answer 22

producing energy

Question 23

catabolism

Answer 23

energy release/use

Question 24

cellular proliferation

Answer 24

increase in number of cells

Question 25

cellular differentiation

Answer 25

cells develop into tissues with specialied structure and function

Question 26

What are the implications in health and disease

Answer 26

Adapt or die

Question 27

Atrophy

Answer 27

decrease in size

Question 28

hypertophy

Answer 28

increase in size

Question 29

hyperplasia

Answer 29

increase in number of cells

Question 30

metaplasia

Answer 30

cell changes in type (GERD in smokers)

Question 31

Dysplasia

Answer 31

change in cell size, shape, uniformity, arragement, and structure (ie mutation in DNA)

Question 32

Apoptosis

Answer 32

programmed cell death

Question 33

Necrotic Cell Death

Answer 33

unregulated death of cells caused by injury
