To Stings And Bites When a foreign substance such as insect venom or saliva is injected into humans, the body s immune system is signaled to attack. It does so by producing antibodies.
Antibodies are our defense against many invading agents.
Histamine when released can cause a number of reactions in humans that can affect the circulatory, respiratory and other body systems. These reactions vary in severity depending on the amount of histamine released. Persons whose immune systems are producing large quantities of antibodies will exhibit more intense allergic reactions. These persons are considered to be hypersensitive. However, once the immune system has been exposed, it becomes sensitized to that particular allergen and future stings or bites may result in similar reactions or even more severe reactions.
