Anticoagulant
Heparin
An alarm substance is a chemical released by an organism in response to a threat or danger. It serves to communicate the presence of a predator or harm to other members of the species, triggering a response such as fleeing or defensive behavior.
Mast cells contain histamine and heparin in their granules. Histamine is involved in allergic responses and inflammation, while heparin acts as an anticoagulant, preventing blood clotting. These granules are released during immune responses, particularly in allergic reactions and in response to injury.
They are released by basophils and mast cells in nearby connective tissue.
Histamine is released primarily during allergic reactions when the immune system identifies a harmless substance as a threat, prompting mast cells and basophils to release it. It is also released in response to injury or inflammation as part of the body's healing process. Additionally, histamine plays a role in regulating gastric acid secretion in the stomach.
Inflammation is the localized response to an injury or tissue destruction. Inflammatory Response inflammation infection, acute inflammation, cachexia

Regeneration is the nonspecific response of the body to injury.
The body's normal response to injury is inflammation, which is a protective mechanism to help initiate the healing process. This response involves increased blood flow to the injured area, immune cell activation, and tissue repair processes. Pain, swelling, redness, and heat at the injury site are common signs of inflammation.
Pain chemicals, such as prostaglandins and cytokines, are released in response to injury or discomfort. They trigger inflammation and send signals to the brain, alerting the body to the presence of potential harm. This helps the body to respond by initiating healing processes and protecting the injured area.
