Study Notes
Reaction of Tissue Injury
- The reaction of tissue injury is caused by the release of chemical mediators, leading to the process of inflammation.
The Process of Inflammation
- Consists of two phases:
- The first phase involves the accumulation of blood in the area of tissue injury due to the release of chemical mediators.
- The second phase involves the leakage of plasma into the interstitial tissue at the injury site.
Five Cardinal Signs of Inflammation
- (Not specified in the provided text, but the five cardinal signs of inflammation are: pain, heat, redness, swelling, and loss of function)
Chemical Mediators of Erythema (Redness)
- The chemical mediators that cause erythema (redness) are:
- These chemical mediators dilate arterioles, leading to increased blood flow to the affected area.
Increase in Capillary Permeability
- Caused by the increase in blood accumulation that results in pyrogens, which are substances that produce fever.
Pyrogens
- Substances that produce fever.
