When a foreign object enters the body, complex chemical and mechanical actions are set into motion. These methods defend and preserve the body’s cells and tissues. The foreign elements are usually a protein and called an antigen. The most popular answer to the antigen is the production of antibody, a protein synthesized by the immune system that can help neutralize pathogens such as bacteria and viruses. The antigen-antibody reaction is an essential component of the complete immune response. Immunity is the balanced state of the body wherein the human body contains adequate biological defences to fight infection, disorder, or unwanted biological invasion. It is also a condition where the body has sufficient tolerance to avoid allergy and autoimmune diseases.

What Are The Different Types Of Immunity?

In easy terms, the umbilical cord is just the connection within the fetus and mother that gives nutrients and oxygen. Immunoglobulins can also be obtained passively through lactation and breastfeeding. The passage of Immune immunoglobulins then heads to the creation of antibodies which are essential in the immune system response. This is one of the major types of immune system.
