1. Acute inflammation: This type of inflammation occurs rapidly and is typically short-lived. It is a normal response to injury or infection and is characterized by symptoms such as redness, swelling, heat, and pain. Acute inflammation is a protective response that helps the body to heal and defend itself against harmful stimuli.
2. Chronic inflammation: Chronic inflammation is a prolonged and persistent inflammatory response that can last for weeks, months, or even years. It can be caused by a variety of factors, including autoimmune disorders, chronic infections, obesity, and long-term exposure to irritants such as tobacco smoke. Chronic inflammation can lead to tissue damage and is associated with a number of chronic diseases, including heart disease, diabetes, and cancer.

Chronic inflammation
- Slow onset, can last for weeks, months, or years - Characterized by: - Infiltration of lymphocytes and macrophages - Proliferation of connective tissue - Tissue destruction and fibrosis
Types of chronic inflammation
- Granulomatous inflammation: Characterized by the formation of granulomas, which are collections of macrophages surrounded by a ring of lymphocytes. - Interstitial inflammation: Characterized by inflammation within the connective tissue. - Ulcerative inflammation: Characterized by erosion of the epithelial surface. - Necrotizing inflammation: Characterized by tissue death.
