Inflammation Worksheet Flashcards
6 possible causes of inflammation:
- physical damage
- chemical exposure
- allergic reaction
- ischemia/infarction
- foreign bodies
- extreme temps
What cells do phagocytosis? (3)
neutrophils, monocytes, and macrophages
___ resleases histamine, causing inflammation
basophils
____ increase in an allergic reaction
eosonophils
___ are active in cell-mediated responses (they tell other cells what to do, like a quarterback)
T-Lymphocytes
____ produce antibodies.
B-lymphocytes (B for anti-Bodies)
prurulent exudate contains more ___, ___, and ___.
leukocytes, cell debris, microorganisms
___ exudate increases the risk of scar tissue.
fibrinous
In this type of healing, damaged tissue is replaced by identical tissue by proliferation of nearby cells.
regeneration
Regeneration is not possible for 3 types of tissue:
nerve tissue, skeletal muscle or cardiac muscle
___ is the process of healing by the formation of connective tissue (fibrous or scar tissue.
replacement
Reasons for slow healing in elderly:
- impaired circulation
- decreased metabolic rate, which slows protein synthesis and cell mitosis
- chronic diseases or medication like steroids taken fro chronic disease
- decreased immune response - predisposes pt to infection, which delays healing
a protein that is the basic component of scar tissue and provides strength for new repair.
collagen
An overgrowth of fibrous tissue consisting of excessive collagen deposits leading to hard ridges of scar tissue or keloids
hypertrophic scar tissue
the percentage of red blood cells in a volume of blood
hematocrit
erosion through the wall
- wall of viscera
perforation
Prednisone decreases the immune response, causes atrophy of ____, decreases the number of ___, and suppresses the ___ response, thus decreasing resistance to infection.
lymphoid tissue, leukocytes, inflammatory
Increases # of WBCs, esp neutrophils
Leukocytosis
Proportion of each type of WBC altered, depending on the cause
Diffferential count
A protein not normally in the blood, but appears with acute inflammation and necrosis withing 24-48 hours
C-reactive protein
Elevated plasma proteins increase rate at which RBCs settle in a sample
Increased Sed Rate
Released from necrotic cells and enter tissue fluids and blood: may indicate the site of inflammation.
Cell enzymes
