Asthma is a disease in which expiration of the lungs is obstructed by two parts One part is by overstimulation of the smooth muscles of the bronchioles, causing the smooth muscles to contract, constricting the airways. The other part of asthma is overproduction of mucus. It is often stimulated by allergies, drastic change in temperature, exercise, and sickness While there is no direct gene linked to asthma, family history tends to show that genetics do play an important factor Eczema' s symptoms consist of dry itchy skin, redness, cracking, oozing and bleeding. Several causes of eczema include allergies, skin irritants, dry weather, and sweat. Similar to asthma, there is also no direct gene linked to asthma, however family history can show that genetics also play an important factor Allergies Both diseases are stimulated by allergies. Allergies is when the human body responds to a harmless foreign particle as a harmful antigen. When an antigen enters a body the plasma cell produces Immunoglobulin e(ge). ige binds to the surface of mast cells. Future exposures to antigen results in binding of antigen to surface bound E. This then leads to mast cells degranulation, releasing steroids histamine and leukotriene Leukotriene promotes contraction the bronchioles, narrowing the air pathway. Histamine increases permeability causing capillary leakage and edema. this causes swelling and greater production of mucus within the air pathways.
