Components of Human Skeleton:
In many species, the immune system can be classified into subsystems, such as the innate immune system versus the adaptive immune system , or humoral immunity versus cell-mediated immunity. Floating also expedites repair and recovery for sore muscles and joints after strenuous activity. Chemical barriers also protect against infection. Some examples of intracellular pathogens include viruses, the food poisoning bacterium Salmonella and the eukaryotic parasites that cause malaria Plasmodium falciparum and leishmaniasis Leishmania spp. This explains why you feel out of breath for a few minutes after a strenuous activity—your body is trying to restore itself to its normal state.

For example, antibodies in a mother's breast milk give a baby temporary immunity to diseases the mother has been exposed to.
This can help protect the baby against infection during the early years of childhood. Everyone's immune system is different. Some people never seem to get infections, whereas others seem to be sick all the time. As people get older, they usually become immune to more germs as the immune system comes into contact with more and more of them. That's why adults and teens tend to get fewer colds than kids — their bodies have learned to recognize and immediately attack many of the viruses that cause colds.
Immunodeficiencies happen when a part of the immune system is missing or not working properly. Immunodeficiencies also can be acquired through infection or produced by drugs these are sometimes called secondary immunodeficiencies. Immunodeficiencies can affect B lymphocytes, T lymphocytes, or phagocytes. Examples of primary immunodeficiencies that can affect kids and teens are:.
Acquired or secondary immunodeficiencies usually develop after someone has a disease, although they can also be the result of malnutrition, burns, or other medical problems. Certain medicines also can cause problems with the functioning of the immune system. In autoimmune disorders, the immune system mistakenly attacks the body's healthy organs and tissues as though they were foreign invaders.
Allergic disorders happen when the immune system overreacts to exposure to antigens in the environment. The substances that provoke such attacks are called allergens. The immune response can cause symptoms such as swelling, watery eyes, and sneezing, and even a life-threatening reaction called anaphylaxis. Medicines called antihistamines can relieve most symptoms. Cancer happens when cells grow out of control.
Leukemia , which involves abnormal overgrowth of leukocytes, is the most common childhood cancer. Lymphoma involves the lymphoid tissues and is also one of the more common childhood cancers. With current treatments, most cases of both types of cancer in kids and teens are curable.
