Final answer:
Immunodeficiency disorders can result from a failure of one component of the immune system.
Step-by-step explanation:
True
Immunodeficiency disorders can result from a failure of one component of the immune system. This can occur when T or B cells, or both, do not work properly, or when the body does not produce enough antibodies.
For example, in severe combined immunodeficiency disease (SCID), individuals are born without functioning B or T cells. Another example is hypogammaglobulinemia, where B cells are affected and can lead to respiratory and gastrointestinal infections.
Therefore, immunodeficiency disorders can indeed be a result of a failure of one component of the immune system.
