The immune system’s main function is to protect against disease or other potentially damaging foreign bodies.
The parts of the immune system are…
Bone Marrow- All the specialized cells of the immune system are formed in the bone marrow, where they mature.
Thymus- This small but important organ is where lymphocyte precursors become thymocytes, which in turn mature into T-cells.
Spleen- You can think of the spleen as a filter for the blood. It catches foreign material in the blood and activates different types of immune system cells.
Lymph Nodes- The lymph nodes filter foreign material from the lymph fluid. Fluid that drains from various tissues in the body collects in the lymph system and passes through the nodes, being filtered as it passes.
T-Cells- There are two subsets of T-cells: CD4 cells and CD8 cells. CD4 cells secrete factors that activate other white blood cells that participate in the immune response.
3 Interesting Facts:
1. Getting under 5 hours of sleep a night has been shown to greatly depress immune function in your body.
2. Studies show that people who lack humor in their lives tend to have less protective immune responses.
3. Toxins such as air pollution, pesticides and even second-hand cigarette smoke can affect your body's natural defense system.
3 Disorders:
1. Immunodeficiency occurs when the immune system is not as strong as normal, resulting in recurring and life-threatening infections. In humans, immunodeficiency can either be the result of a genetic disease such as severe combined immunodeficiency, acquired conditions such as HIV/AIDS, or through the use of immunosuppressive medication
2. In response to an unknown trigger, the immune system may begin producing antibodies that instead of fighting infections, attack the body's own tissues.
3. The immune system attacks the nerves controlling muscles in the legs and sometimes the arms and upper body. Weakness results, which can sometimes be severe.
What other systems this systems with? Why/How
The immune system actually works with is the circulatory system. You could say this because the main mode of transport for immune cells are the blood vessels. The circulatory system allows immune cells to travel throughout the body and survey for infection.
