Detailed explanation-1: -Answer and Explanation: The immune system helps to maintain homeostasis because it removes pathogens that would otherwise cause disease in the body, which is the opposite of homeostasis. Homeostasis is a stable, internal state within the body.
Detailed explanation-2: -White blood cells are the key players in your immune system. They are made in your bone marrow and are part of the lymphatic system. White blood cells move through blood and tissue throughout your body, looking for foreign invaders (microbes) such as bacteria, viruses, parasites and fungi.
Detailed explanation-3: -The lymphatic system and lymph nodes (small bean-shaped organs clustered in the neck, armpits, abdomen and groin) act as filters and trap harmful germs. If immune cells in the lymph node recognize pieces of a germ, they will activate, replicate and leave the lymph node in search of those harmful germs.
Detailed explanation-4: -Innate immune cells recognize certain molecules found on many pathogens. These cells also react to signaling molecules released by the body in response to infection. Through these actions, innate immune cells quickly begin fighting an infection. This response results in inflammation.
Detailed explanation-5: -Organs and tissues important to the proper functioning of the immune system include the thymus and bone marrow, lymph nodes and vessels, spleen, and skin.
