Answer 1

The immune system is made up of special cells, proteins, tissues, and organs that defend people against germs and microorganisms every day. In most cases, the immune system does a great job of keeping people healthy and preventing infections. But sometimes problems with the immune system can lead to illness and infection. The cells involved are white blood cells, also referred to as leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances. The defense cells are produced or stored in many locations in the body, including the bone marrow, thymus, and spleen. For this reason, these storage areas are called the lymphoid organs. There are also clumps of lymphoid tissue throughout the body, primarily known as lymph nodes that house the defense cells. The defense cells circulate through the body between the organs and nodes via blood and lymph. In this way, the immune system works in a coordinated manner to monitor the body for germs or substances that might cause problems. When antigens (foreign substances that invade the body) are detected, several types of cells work together to recognize them and respond. These cells trigger the B lymphocytes to produce antibodies, specialized proteins that lock onto specific antigens. Once produced, these antibodies continue to exist in a person's body, so that if the same antigen is presented to the immune system again, the antibodies are already there to do their job. So if someone gets sick with a certain disease, like chickenpox, that person typically doesn't get sick from it again. This is also how immunizations prevent certain diseases. Immunodeficiency occurs when the immune system is less active than normal, resulting in recurring and life-threatening infections such as tuberculosis, hence the use of immunosuppressive medication known as ARVs. In contrast, autoimmunity results from a hyperactive immune system attacking normal tissues as if they were foreign organisms. Such cases include Hashimoto's disease.
