The allergic response is a result that shows an overreaction of the immune system to a previouly encountered antigen and the system is to protect the body from potential harm.
What happens and the condition
An Allergy is a harmless substance that will affect the immune system but the second time the person touches is when the immune system over reactions it thinks it is harming the body being the antigen, there are things that can cause an allergic reaction and they are antigens called allergens, The immune system produces white blood cells called lymphocyte they are always in the bloodstream they are responsible to protect the body against invaders and the two different types are T cells and B cells as the antigen enter the body or have touched the body these allergens trigger and release specific antibodies (immunglobulin, IgE) which attack specific antigens they are in the blood stream they then attach themselves to mast cells which are white blood cells and release histamines and heparine which fight the invader and act as symptoms of the allergic reaction. This may cause a runny nose, sneezing, breathing difficulty etc. It is even possible to lead to death if not careful.
Components of the immune system
As the allergen has entered and the components of the immune system involved in the allergic response is when the allergen becames 'dangerous' to the body and the immune system release immunglobins basophils and mast cell which
release histamine and heparin. The histamine contract smooth muscles that tend to cause diffulty breathing in the lungs/capillaries as it is decreased in diameter or another way it causes blood vessels to dilate causing swelling inflaming, heat and redness.
Normal body functioning affected
When an antigen enters or touches the body if a person who is allergic to that substance it is know the immune system to over react and for a person is not allergic to the substance it will have no reaction it does not over react the body does not release basophils unless the allergic reponse is inplay . When someone does not have the allergic reaction means they dont have the reaction of redness or difficulty breathing etc. What happens with a normal immune stystem that is not allergic to a substance the body just produces B cells to try kill that antigen so it does not spread and damage/infect the body it does not produce immunglobulin and mast cells which are the cells that kill antigens and the result of an allergic response.
Treatments: It is recommended people who have allergies to try stay away from those allergies, but there are medications such as antihistamines which block and stop histamines from being activated and stop allergic symptoms, theywork with seasonal allergies, food allergies but do not always work.
