immune system structures, chronic disorders, arteriosclerosis, "hardening, the arteries", infections, autoimmune disorders, cancer, increased risk caused, in part, by the nature of these disorders, the chronic disorders arteriosclerosis develop slowly, not show symptoms, they have been progressing, another significant part of this increased risk is probably related to aging changes, in the immune system, immune system protects against diseases, seeks out, destroys viruses, bacteria, fungi, cancerous cells, damage the body, learns to tell the difference, "self" tissue, normal body cells, "non-self" particles, foreign invaders, abnormal cells, aging changes, thymus, the organs, the immune system, the site where certain immune cells, t lymphocytes, "t cells", mature, thymus begins to shrink, atrophy, after adolescence, by middle age it is only, 15% of its maximum size, the t cells directly kill foreign particles, others help coordinate other parts, the immune system, specialized to attack different types of infections, the number of t cells, does not decrease, aging, t cell function decreases, a weakening, the parts, the immune system, controlled by these t cells, effect of changes, steady decrease in immunity after young adulthood, body is exposed to bacteria, microorganisms, actual exposure, by immunization, fewer protective antibodies formed, formed at a slower rate, flu shots, immunizations less effective, protection, not last, expected, later in life, immune system also seems to, become less tolerant, the body's own cells, an autoimmune disorder develops, normal tissue is mistaken, non-self tissue, immune cells attack certain organs, tissues, immune system becomes less able to detect malignant cells, cancer risk also increases, immune system also becomes less able to detect foreign particles, infection risk is greater, things also increase the risk of infections, sensation changes, gait changes, in the skin structure, "normal aging changes" increase the risk of injury, bacteria, enter broken skin, illness, surgery, further weaken the immune system, making the body more susceptible to subsequent infections, diabetes, is also more prevalent, lead to decreased immunity, besides slightly decreasing immunity, aging also affects inflammation, wound healing, inflammation, immune response, the immune system thinks there is trouble, sends more cells, site, the problem, swelling, pain, redness, warmth, irritation, the hallmarks of inflammation, inflammation often indicates infection, due to autoimmune attack on "self" tissue, many older people heal more slowly, directly related to changes, in the immune system, a consequence of other problems diabetes, arteriosclerosis, leads to decreased blood flow to some parts, the body the lower extremities, many older people take anti-inflammatory medications, to control conditions arthritis, known to slow wound healing, common problems, increased infection risk, decreased ability to fight diseases, slowed wound healing, autoimmune disorders, cancer, disease prevention, routine immunizations, prevent illness in children, a few routine immunizations, we get older, adult tetanus, td, immunizations, given every 10 years, a booster given sooner, dirty wound, recommend other immunizations, pneumovax, prevent pneumonia, its complications, flu vaccine, hepatitis immunization, optional immunizations, not necessary, all older people, keeping generally healthy also helps, maintaining good health involves, exercise, eat a well-balanced diet, stop smoking, minimize alcohol use, moderate drinking seems to have some health benefits, excessive drinking, cause serious damage, use safety measures to avoid falls, injuries, related topics, aging changes in hormone production, aging changes in organs, tissues, cells.
