Chemicals produced by damaged tissues and white blood cells that stimulate the immune response are known as cytokines and chemokines. These signaling molecules help regulate inflammation, attract immune cells to the site of injury or infection, and facilitate communication between different immune cells. Additionally, they play a crucial role in initiating and coordinating the body's defense mechanisms against pathogens and promoting tissue repair.
Prostaglandins are released by damaged tissues and stimulate nerve endings to produce the sensation of pain. They also cause inflammation and fever as part of the body's immune response to injury.
A burn continues to hurt even after the heat source is removed because the damaged tissue releases chemicals that stimulate pain receptors in the skin. Additionally, the body's inflammatory response to the burn can further exacerbate the pain sensation.
called chemotaxis. Chemicals released from damaged cells act as signals that guide leukocytes to the site of injury or infection, helping to initiate the inflammatory response and target the source of damage for immune defense and repair.

When chemicals are released from a damaged cell, inflammation is typically initiated as part of the immune response. This process helps to isolate and eliminate pathogens and start the repair process. White blood cells are recruited to the site of injury to protect against infection and promote healing.
A damaged or weakened pathogen is one that has been altered in a way that reduces its ability to cause disease. This can be achieved through processes like heat treatment or genetic modification. These weakened pathogens can be used in vaccines to stimulate an immune response without causing illness.
Positive chemotaxis refers to the movement of cells in response to the presence of a chemical gradient. In the case of damaged cells, the release of specific chemicals acts as a signal for other cells to migrate towards the site of injury. This helps in the recruitment of immune cells and facilitates the repair process in tissues.

When the body is healing, it releases histamines and other chemicals that can cause itching as part of the inflammatory response. This itching sensation is a normal part of the healing process as the body works to repair and regenerate damaged tissues.
Following an insect bite, the damaged tissue typically undergoes an inflammatory response. This leads to the release of histamines and other chemicals, resulting in swelling, redness, and pain at the site. Immune cells are recruited to the area to fight potential infections and facilitate healing. Ultimately, the tissue may regenerate, and any remaining symptoms usually resolve as the inflammatory response subsides.
