Definition of inflammation

Protective measure to remove the cause of injury/invasion and any consequences from the body

Signs of inflammation

Redness, swelling, heat, pain, function loss

Acute inflammation triggers

Infection, trauma, physical or chemical, tissue neurosis, foreign bodies, and Immune reaction

Inflammation stages: vascular and cellular

Vascular - vasoactive changes: Vasoconstriction followed by dilation of blood passages. Immediate reaction from Histamine activation


Cellular - leucocytes, allow emigration from endothelial cells to tissue and pahgocytocis
