What is involved in the development of the immune system?

The immune system has the task of protecting the body from all foreign antigens. The development of the immune system occurs in the stages. It starts during growth in the mother's womb and continues until death. Three types of immune responses are developing: natural immunity during fetal development, adaptive immune response after birth before exposure to antigens and passive immune responses from other sources.

Before the birth of people, many parts of the body must develop to survive outside the womb. Vascular, respiratory and digestive systems develop for the preparation of children for life in the world. The development of the immune system begins during the growth of the unborn child. The fetus is exposed to antibodies from the mother and the immune system develops resistance before birth. This is classified as a natural immunity that protects infants from disease and disease, because their fine immune systems progress in the development of outside the womb.

Adaptive immune response occurs after Birth. The development of the immune system for this type of reaction occurs by exposure to antigens. Over timeIt develops an adaptive immune response. After exposure, the body becomes immune to specific antigens. Vaccination is a way to create immunity.

Unlike the natural immunity, which is present before birth, there is a passive immune response from other sources, such as passing antibodies from mother to child in breast milk. There are some cases when using inoculation. Inoculation involves artificially induction of antibodies production. This triggers the immune response to a particular antigen much earlier than if the immune system could react itself.

Although the development of the immune system is constantly occurring during human life, there are some cases that lead to disruption of the immune system. Such cases include genetic imports Mune, autoimmune disorders and acquired immune disorders.

genetic immune disorders are commonly present before or immediately after birth. These immunityDisorders, which are also called primary disease of immune deficiency, are obvious if repeated cases of the same disease occur. Diseases are often common, such as ears' infections, and can be treated for rapid identification.

Autoimmune disorders are another complication for the development of the immune system. The autoimmune disorder causes the body to think that its own tissues are foreign antigens. Rheumatic fever and arthritis are common forms of these disorders.

The

acquired immune disorders are not hereditary, but can be passed from mother to child during birth or breast milk. These disorders, such as human immunodeficiency virus, cause the overall development of children. The development of the immune system is stopped and the body does not have the ability to prevent anti -help diseases.
