The warmth and redness associated with the inflammatory response are a result of which of the following?
increased interstitial fluid
production of complement
white blood cells in area
increased blood flow
The Correct Answer is D
A. increased interstitial fluid: Increased interstitial fluid (edema) causes swelling (tumour) rather than the warmth and redness of inflammation.
B. production of complement: Complement proteins contribute to inflammation (opsonization, cell lysis) but are not the direct cause of the warmth/redness.
C. white blood cells in area: Leukocyte accumulation contributes to pain and loss of function but is not the main cause of the heat and redness.
D. increased blood flow: Vasodilation of arterioles increases blood flow to the injured area, producing the local warmth (calor) and redness (rubor).
