Question: What are the five hallmarks of inflammation?
The five hallmarks of inflammation are:
1. Vasodilation: This is the process by which the capillaries and vessels of the circulatory system widen to allow increased blood flow.
2. Margination: This is the process by which white blood cells, such as neutrophils, move from the blood vessels to the site of infection or injury.
3. Chemotaxis: This is the process by which certain immune cells move in response to a chemical signal called a chemokine.
4. Phagocytosis: This is the process by which certain immune cells, such as macrophages, engulf and digest bacteria, cellular debris, and other invaders.
5. Release of inflammatory mediators: This is the process by which immune cells, such as mast cells and basophils, release molecules, such as cytokines, which further promote the inflammatory response by attracting additional immune cells to the site of infection or injury.
Overall, inflammation is an important immune response to protect the body and is characterized by these five main features.
