SLCC Pathophysiology Exam with correct
answers
Body's ability to maintain dynamic steady state of internal balance -
🔰CORRECT ANSWERS ✔✔Homeostasis
Increased number of cells - 🔰CORRECT ANSWERS
✔✔Hyperplasia
Increased size of cell - 🔰CORRECT ANSWERS ✔✔Hypertrophy
Reduced size of cell - 🔰CORRECT ANSWERS ✔✔Atrophy
Replacement of one cell type with another that can better endure
stress but not as effective as original tissue. i.e. scar tissue, callous -
🔰CORRECT ANSWERS ✔✔Metaplasia
Abnormal cell growth results in abnormal size shape or
appearance, precedes cancerous changes - 🔰CORRECT
ANSWERS ✔✔Dysplasia

,Three mechanisms of cellular injury - 🔰CORRECT ANSWERS
✔✔Free radical injury
Hypoxic cell injury
Impaired calcium function
Highly reactive chemical molecules with an unpaired electron in
their outer orbit that pulls electrons off of healthy cell molecules >
cell damage; cancers; other disease states result. - 🔰CORRECT
ANSWERS ✔✔Free Radical Injury
cellular oxygen deprivation. Brain/Heart/Kidneys are high
consumers of O2. Caused by lack of O2 or impaired blood flow to
the tissue > inflammatory response - 🔰CORRECT ANSWERS
✔✔Hypoxic Cell Injury
Ca++ is an important signalling ion for many cell responses. If the
cell is injured, calcium builds up inside the cell and many cell
structures are damaged. - causing? - 🔰CORRECT ANSWERS
✔✔Impaired Calcium Function
causing inappropriate activation of cellular enzymes
2 \\\\\\/ \\\\\\

,Causes impaired cell function but NOT DEATH. Body can repair
itself and return to normal homeostasis if the injury is reversed in
time before cell death results - 🔰CORRECT ANSWERS
✔✔Reversible cell injury
Three types of reversible cell injury - 🔰CORRECT ANSWERS
✔✔Water
Lipids
Calcium
abnormal amounts of?
Sodium builds up in cell due to the breakdown of the sodium
[Na+] - potassium [K+] pump. Consequently, sodium collects
inside the cell and attracts water > intracellular swelling. Usually
due to hypoxic injury. - 🔰CORRECT ANSWERS ✔✔Water
Abnormal amounts of?
collects in cells leading to impairment of cell functions. "Fatty liver"

, is often the result. Fatty changes are a more ominous sign of cell
injury than swelling, but can be reversed with dietary changes. - 🔰
CORRECT ANSWERS ✔✔Lipids
Abnormal amounts of?
builds up in cell due to breakdown of the Calcium [Ca++] -
Magnesium [Mg++] pump. Consequently, calcium collects inside
the cell and causes inappropriate activation of cellular enzymes >
damages cell internally. - 🔰CORRECT ANSWERS ✔✔Calcium
Controlled cell death by implosion. Membrane maintains integrity,
cell contents not released into extracellular space, no inflammatory
response. - 🔰CORRECT ANSWERS ✔✔Apoptosis
How long do WBCs live? - 🔰CORRECT ANSWERS ✔✔8-10 days
How long do RBCs live? - 🔰CORRECT ANSWERS ✔✔3 months
Uncontrolled cell death. Membrane looses integrity, cell contents
released into extracellular and inflammatory response. - 🔰
