1. Inflammation is the body's response to infection, irritation, or injury, characterized by redness, swelling, heat, and pain. It involves the immune system and blood vessels. 2. Acute inflammation is a short-term response to recent injury or infection, marked by increased blood flow, blood vessel permeability, and migration of white blood cells. Chronic inflammation is a long-term response involving lymphocytes, macrophages, and fibrosis. 3. Inflammation can resolve, lead to abscess or fibrosis, and is mediated by chemical signals like histamine, bradykinin, prostaglandins, and cytokines. Different cell types and patterns characterize specific inflammatory diseases.

8. : CELLS OF INFLAMMATION

30. Acute inflammation - Acute pneumonia - lung. Almost every alveolar space is filled with cellular infiltrate. There is hardly any air space left in the lung

31. Acute inflammation - Acute pneumonia - lung. An abundance of eosinophilic material (neutrophils) with fine strands are present in the alveolar space.

32. Inflammatory infiltrate, fluid with fibrin into the alveolar spaces

33. Acute fibrinous pericarditis

34. the yellowish fluid in this opened pericardial cavity is a purulent exudate.
