WHAT IS PATHOLOGIC CHANGE
Structural changes in cells
WHAT IS PATHOPHYSIOLOGIC CHANGE
FUNCTIONAL CHANGES IN CELLS
WHAT IS THE DEFINITION OF DISEASE
A CONDITION IN WHICH SOME FUNCTIONAL, BIOMECHANICAL, OR GENETIC ABNORMALITY OF THE BODY CAUSES A LOSS OF NORMAL HEALTH.
WHAT ARE THE 4 ASPECTS OF DISEASE THAT PATHOLOGY FOCUSSES ON
AETIOLOGY PATHOGENESIS MORPHOLOGY CLINICAL MANIFESTATION
WHAT CAUSES CELL PATHOLOGY
changes in the environment cause cells to become stressed which leads to a loss of homeostasis, causing the need for cells to adapt.
T OR F? CELLULAR RESPONSE CAN OCCUR IN BOTH NORMAL AND ADVERSE CONDITIONS?
TRUE
CELLULAR ADAPTATIONS TO ADVERSE CONDITIONS ARE GENERALLY ONLY SUCCESSFUL FOR A ____ AMOUNT OF TIME
SHORT
WHAT HAPPENS IF CELLULAR STRESS IS TO SEVERE OR LONG TERM?
IT WILL EVENTUALLY OVERWHELM THE ADAPTIVE PROCESSES AND CELLULAR INJURY/ DEATH WILL OCCUR
WHAT ARE THE TWO TYPES OF CELLULAR INJURY
REVERSIBLE AND IRREVERSIBLE
CELLULAR AGEING CAUSES __________ AND __________ CHANGES THAT MAY LEAD TO CELL DEATH
STRUCTURAL, FUNCTIONAL
A CELLS STRESS RESPONSE DEPENDS ON?
TYPE INTENSITY DURATION
HOW CAN THE EFFECT OF CELLULAR STRESS BE MEASURED
BY MEASURING AND OBSERVING THE PERFORMANCE OF THE TISSUE, ORGAN, OR ORGAN SYSTEM
WHAT ARE THE 6 CASUES OF CELLULAR INJURY
HYPOXIA CHEMICAL AGENTS NUTRIITONAL IMBALLANCES PHYSICAL AGENTS INFECTION AGENTS GENETIC CAUSES
WHAT IS HYPOXIA
LACK OF SUFFICIENT OXYEGN INTO THE CELL
WHAT IS THE MOST COMMON CAUSE OF CELL INJURY
HYPOXIA
WHAT IS THE MOST COMMON CAUSE OF CELL HYPOXIA
ISCHEMIA - RESTRICTION OF BLOOD FLOW
WHAT IS CHEMICAL CELL INJURY
DIRECT CONTACT OF TOXIC CHEMICALS TO THE CELLULAR MEMBRANE OR ORGANELLES THAT DAMAGE IT
WHAT IS A NUTRITIONAL IMBALANCE
WHEN THERE IS A DEFICIENCY OR OVER SUPPLY OF CERTAIN NUTRIENTS TO THE CELLS

HYPOTHERMIC OR HYPERTHERMIC INJURY ATMOSPHERIC PRESSURE UV TRAUMA
2 EXAMPLES OF CELL INJURIES CAUSED BY PHYSICAL AGENTS
SPRAINS AND STRAINS BURNS FROSTBITE
WHAT DO INFECTIOUS AGENTS DO TO CELLS
CAN ENTER THE BODY AND CAUSE WIDESPREAD OR LOCAL DAMAGE OR MAY ENTER THE CELL AND RELEASE TOXINS THAT ARE HARMFUL TO THE CELL
