Tulehdusprosessiin

Tulehdusprosessiin refers to the inflammatory response of the body to infection or injury. It is a complex process involving various cells, chemicals, and tissues. When the body detects harmful substances, such as bacteria or damaged cells, it initiates an inflammatory response. This process is mediated by the immune system, which includes white blood cells and other defense mechanisms.

The initial phase of the inflammatory response involves the release of histamines and other chemicals from mast cells. These substances cause blood vessels to dilate, increasing blood flow to the affected area and enhancing the delivery of immune cells. Neutrophils, a type of white blood cell, are among the first to arrive at the site of infection or injury. They engulf and destroy pathogens, a process known as phagocytosis.

In the second phase, macrophages, another type of white blood cell, take over. Macrophages are more efficient at engulfing and destroying pathogens than neutrophils. They also release cytokines, which are signaling molecules that recruit more immune cells to the site. This phase is crucial for clearing the infection and initiating the healing process.

The final phase of the inflammatory response involves the resolution of inflammation. This is achieved through the action of anti-inflammatory cytokines and the removal of dead cells and debris. The affected tissues are repaired, and the body returns to its normal state. If the inflammatory response is not properly regulated, it can lead to chronic inflammation, which is associated with various diseases, including arthritis and cardiovascular disease.
