manifestations of cellular injury Flashcards
describe swelling
accumulation of water, lipids, carbohydrates, glycogen, proteins,
calcium, bilirubin etc.

by crowding the organelles and causing harmful
metabolites to be produced during catabolism (energy releasing process)
describe redness

what are the systemic manifestations of cellular injury
fever (warmth)
leukocytes
pain
elevated heart rate
what is another name for redness
erythema
what do prostaglandins do
signals that there is pain
what happens during exocytosis of histamine and how does it promote inflammation
by increasing blood flow to affected area by widening blood vessels (vasodilation) (swelling)
what can the release of histamine cause
allergy symptoms and inflammation
what does widening blood vessel increase during an injury
increase blood in affected areas to bring white blood cells to the area; this brings blood vessels closer to the skin
what is considered a fever
when temperature is 2 points above baseline( normal)
what role does a fever have
kill by heat
