Main function The immune system is made up of a network of cells, tissues, and organs that work together to protect the body

Main parts of the system Thymus - lymphoid organ situated in the neck that produces T cells. White blood cells - cells of the immune system that protect the body from infectious disease. Antibodies - a blood protein produced in response to counteract a specific antigen. Antigens - a toxic foreign substance in the immune system.

Main parts of the system Epidermis - outer layer of cells covering an organism. Cilia - serves as a sensory organelle. Mucus - secreted by mucus membranes and glands for lubrication. Saliva - watery liquid secreted into the mouth by glands for aiding, swallowing, and chewing. Pathogens - bacteria or virus or other microorganism.

Main parts of the system Allergy - a damaging immune response by the body to a substance. Histamines - organic nitrogenous compound involved in immune response. Vaccination - biological preparation providing immunity to disease.

How do vaccinations work? Vaccinations prepare the body to fight disease without exposing it to disease symptoms. Vaccinations only work for viruses Examples of diseases prevented through vaccinations: Chicken pox - an infectious disease causing a mild fever and a rash of itchy inflamed blisters. Tetanus - bacterial disease marked by rigidity and spasms of the voluntary muscles. Small pox - an acute contagious viral disease, with fever and pustules usually leaving permanent scars.

How the immune system affects other body systems The immune system is like a small police force and it is always patrolling every organ and tissue in the body The immune system works with the circulatory system for transportation needs and the lymphatic system.

How other body systems affect the immune system The circulatory system consists of the blood vessels and heart, with major pathways needed for immune cells to travel. Without a healthy circulatory system, it would be hard for immune cells to travel around the body to do its job.

Two diseases of the immune system AIDS - a disease in which there is a severe loss of the body's cellular immunity, greatly lowering the resistance to infection and malignancy Cancer - the disease caused by an uncontrolled division of abnormal cells in a part of the body.

Effects of outside / environmental factors of the system Germs - a germ is a microorganism (such as bacteria or viruses) that can cause disease which can weaken the immune system. Stress can weaken the immune system because it creates chronic inflammatory conditions such as anxiety, depression, and sleep problems. AIDS is a sexually transmitted disease from another person. There is a severe loss of the body's cellular immunity which lowers the resistance to infection.

Fun facts about the immune system The bone marrow is where white blood cells are produced; lymph nodes then produce and store infection-fighting cells throughout the body. Vaccines work by stimulating the immune system to produce antibodies against a foreign invader without actually infecting the individual with the disease. As a result, when the body encounters that infection in the future, it knows how to fight it off.

Fun facts about the immune system Some research suggests that optimism can actually make our immune system work better. The more happier, or positive you are, the more likely you are to eat right and be less stressed, which will help your immune system.

Instead of using chemotherapy, doctors are starting to use immunotherapy A few years ago, they would have suggested chemotherapy. Instead, oncologist Dr. Matthew D. Hellmann recommended an experimental treatment: immunotherapy. Rather than attacking the cancer directly, as chemo does, immunotherapy tries to rally the patient’s own immune system to fight the disease.

How the immune system helps maintain homeostasis Homeostasis is the tendency toward a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. The immune system maintains homeostasis by preventing pathogens from disrupting the body's normal functioning.

Conclusion The immune system is your bodies defense against infection and illness. It recognizes the cells that make up your body and will try to get rid of anything unfamiliar. It destroys germs and parasites which can be harmful to our body. Without our immune system, we wouldn't be able to survive.
