Knowledge about the disease and its predisposing causes for development would help researchers to better target future therapies. (Bollmeier, 2013) Asthma is a complex syndrome characterised by airway hyper-responsiveness and is caused by a multicellular inflammatory reaction that leads to airway obstruction. Inflammatory and cellular infiltration of the airways is by recruitment and activation of mast cells, macrophages, antigen presenting dendritic cells, neutrophils, eosinophils and T lymphocytes. The major role in the activation of the immune system that leads to the release of many mediators such as interleukins and granulocyte macrophage colony stimulating factor is by type 2 T helper cells. Cells and tissues in asthmatics are prone to inflammatory reactions against normally harmless substances. This inflammation can cause swelling, mucous production leading to airway narrowing. Air narrowing leads to asthma triggering symptoms. Exposure to substances that trigger reactions on the airways lead to production of IgE antibodies that help release of inflammatory mediators such as histamine and leukotrienes. These mediators cause the airway of the smooth muscles

This is so because whenever I am with them and my parents are not around, I take the full responsibility of being a parent to them. Although being away from my family is not for a bad course, I do not get that full satisfaction I usually get when being around them. Staying away from them has made realize how important my family is and that distance plays an important role in strengthening a family as a unit. Â   My extended family plays an important role just like my nuclear family. Even though being away from them too, I cannot get enough of their calls and the precious gifts they send me often. They shower me with love that rivals that of my dad, mum, and siblings. This is a clear example of how a family should be, not even friends can rival that bond created by family members.
