Acute inflammation is the initial physiological response to tissue damage, such as that caused by mechanical, thermal, electrical, irradiation, chemical, or infective insults. It can be acute (lasting for a few days) or chronic (in response to an ongoing and unresolved insult). Inflammation can develop into permanent tissue damage or fibrosis.
Different morphological types of acute inflammation include:
1. **Catarrhal inflammation:** A surface inflammation associated with greatly increased secretion of clear mucus. Later, polymorphs appear.
2. **Hemorrhagic inflammation:** Inflammation with bleeding.
3. **Suppuration:** Inflammation with pus formation.
4. **Serous inflammation:** Inflammation with fluid accumulation.
5. **Fibrinous inflammation:** Inflammation with fibrin deposition.
6. **Pseudomembranous inflammation:** Inflammation with a false membrane formation.
7. **Ulcer:** Inflammation with tissue loss.
Several things can cause chronic inflammation, including: 1. Untreated causes of acute inflammation, like an infection or injury. 2. An autoimmune disorder, which involves your immune system mistakenly attacking healthy tissue. 3. Long-term exposure to irritants, like industrial chemicals or polluteRead more
