SLCC Pathophysiology Exam 1 with correct
answers
Increased number of cells - 🔰CORRECT ANSWERS
✔✔Hyperplasia
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
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
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
How long do WBCs live? - 🔰CORRECT ANSWERS ✔✔8-10 days
