Extract of sample "Immunology and Autoimmunity Disease"
Murphy, 2012 refers to the immune system as a collection of various cells, tissue as well as organs that combine with function. The cells, tissues, and organs have a core role of guarding the human body against invasion by infectious microorganisms such as certain bacteria, fungi, parasites, and parasites (Murphy, 2012).
The vitality of the immune system in human beings is best underscored when people born with particular defects in their human systems are observed with perpetual health challenges. In such individuals who have challenges with their immune systems, physicians have often established that either the system does not function completely, or that only certain components of the system can function, which is referred to as Immunodeficiency (Murphy, 2012). Individuals with immunodeficiency conditions are often extremely prone to attacks by many infectious organisms, which tend to be more fatal.
Roitt (1948) adds that the immune system represents a complex network of effector cells, molecules, tissue, and organs that work as a group to detect millions of different pathogens and distinguish foreign (non-self) cells from the body’s cells. More particularly, the detection of any foreign body within the system usually causes a reaction from the immune system in an attempt to suppress its growth and activities within the body (Roitt, 1948). Most of the time, the body has the remarkable ability to remove abnormal cells, including malignant ones, and to protect the body from infectious agents and damage caused by hazardous substances (Roitt, 1948). A further function of the immune system is to promote the normal functioning of the body, such as in wound repair. However, malfunctions of the immune system may lead to an abnormal response to the body’s tissue, causing problems such as autoimmune disease hypersensitivities or immune deficiency (Roitt, 1948).
The human immune system is one of the most complex systems in the human body, which consists of several functional parts.
