Necrosis = [blank_start]unregulated[blank_end] cell death due to injury
[blank_start]Passive[blank_end] process
Indiscriminate with bystander damage
Membrane [blank_start]blebs[blank_end] but then breaks down
Cell bursts ([blank_start]lysis[blank_end]) and spills contents → inflammation
Activated by toxins released/macrophages
Answer
unregulated
Passive
blebs
lysis

Question
Types of necrosis:
1. [blank_start]Coagulative[blank_end] :
ghost-like appearance
inadequate blood supply
denatured proteins inside cell due to acidified cytosol
2. [blank_start]liquefactive[blank_end]
pus is the appearance
lipid rich tissue will result in this
cell proteins digested and structure is lost
3. [blank_start]caseous[blank_end]
Cheese-like appearance
granulomatous inflammation
4. [blank_start]gangrenous[blank_end]
slow vascular blockage
(dry is [blank_start]coagulative[blank_end] necrosis in the extreme)
(wet is infection and is [blank_start]liquefactive[blank_end] necrosis)
5. Fat
[blank_start]chalky[blank_end] deposits
fatty tissue damaged and fatty acids are released into surrounding tissue
