Pathology Chapter 2

The correct answer is acute inflammation because the image shows trilobed neutrophils, which are characteristic of acute inflammation. Chronic inflammation is characterized by the presence of mononuclear cells like lymphocytes and plasma cells. Fibrosis is the formation of scar tissue, typically seen as collagen deposition. Necrosis is cell death with characteristic features like swelling, nuclear changes, and loss of cellular detail, different from the inflammatory process shown in the image.

The correct answer describes the cellular infiltrates seen in the infarcted myocardium, specifically the early neutrophilic and later mononuclear infiltrates.

Emigration is the process by which white blood cells, such as neutrophils, move from the blood vessels to the site of tissue damage or infection by adhering to the blood vessel walls (margination) and passing through the vessel walls (diapedesis). Phagocytosis, Chemotaxis, and Opsonization are all different processes involved in the immune response but are not specifically related to the movement of neutrophils in this context.

Exudation specifically refers to the process described in the question, where fluid with fibrin and PMN's is released into a specific area due to vasodilation.

Acute inflammation is characterized by the exudation of fibrin, where a fibrin mesh in fluid with PMN's leads to the 'tumor' or swelling seen in acute inflammation. Other features mentioned in the incorrect answers are not specific to acute inflammation.

The term 'Id.' in medical jargon specifically refers to toxin-induced superficial mucosal damage, not any of the other options provided.

The correct answer describes the classic histological finding of acute cholecystitis, which includes neutrophil infiltration. Lymphocytes, eosinophils, and fibrosis are not typical findings in acute cholecystitis.

Granulomatous inflammation is a specific type of chronic inflammation characterized by the formation of granulomas. These granulomas are commonly seen in diseases like tuberculosis (TB) and sarcoidosis, but not in other conditions like COPD, IBD, or Raynaud's disease.

ID is the abbreviation for 'foreign body granuloma', which is a common term used to refer to a reaction of the body to a foreign substance or material that has been implanted or introduced into the body.

Broncopneumonia is characterized by exudative inflammation in the alveoli, involving cells with neutrophils.

Granulomatous inflammation is a specific type of chronic inflammatory response characterized by the formation of granulomas.

Interstitial inflammation with diffuse mononuclear infiltrate is a common response to viral infectious agents, leading to conditions such as myocarditis and viral hepatitis.

A leukemoid reaction is a benign, reactive condition where the body produces an increased number of white blood cells in response to an infection. This can be characterized by a left shift in the white blood cell count along with the presence of toxic granules.
