Diseases & Vaccines
| Term | Definition |
|---|---|
| Diseases caused by viruses | Colds, the flu (Influenza), measles, mumps, Mono, Hepatitis, AIDS, Norovirus, Chicken Pox, West Nile |
| Diseases caused by bacteria | Tuberculosis, tetanus, sinus infections, strep throat, meningitis, salmonellosis, e. coli, ear infection, whooping cough |
| Diseases caused by fungi | Athlete’s foot & ringworm |
| Antibiotic | A medication that destroys or slows the growth of bacteria and helps heal infections. |
| Controllable Risk Factors | Diet, body weight, levels of activity, levels of sun exposure, chemical abuse |
| Uncontrollable Risk Factors | Age, gender, ethnicity, heredity |
| Immunity | The body's ability to destroy pathogens that it has previously encountered. |
| Long term strategies for preventing diseases | Getting immunized, avoiding stress, exercising regularly, healthy diet, get regular medical checkups |
| Vaccine | A dead or nontoxic part of a pathogen that is injected into a person to train his or her immune system to eliminate the live pathogen. |
| Herd Immunity | Large group of individuals in a community being immunized against a contagious disease. |
| Carcinogen | A substance capable of causing cancer in living tissue. |
| Malignant Tumor | Invades and destroys healthy tissue |
| Bacterial Infections | Diseases that destroyed by the immune system or treated with antibiotics. |
| Infectious Disease | A disease that can be passed from one person to another. |
| Antibiotic Resistance | A condition in which bacteria can no longer be killed by a particular antibiotic. |
| Insulin | A hormone that causes cells to remove glucose from the bloodstream. |
| Risk Factor | An attribute, characteristic or exposure of an individual that increases the likelihood of developing a disease or injury. |
| Lifestyle diseases | Diseases that are caused partly by unhealthy behaviors and partly by other factors, such as genetics. |
| High Blood Pressure | when blood pressure is abnormally high especially in the arteries. Can injure the walls of the blood vessels, which can lead to other heart diseases. |
| Stroke | Sudden attacks of weakness or paralysis that occurs when a blood vessel in the brain burst or becomes blocked. |
| Heart Attack | A sudden loss of blood flow to the heart muscle. |
| Cancer | A disease caused by uncontrolled cell growth. |
| Diabetes | disorder in which cells are unable to obtain glucose from the blood such that high blood-glucose levels result. |
| Atherosclerosis | A disease characterized by the buildup of fatty materials on the inside walls of the arteries. |
| How does immunity to a disease develop (3 steps)? | 1- Inject dead or weakened germ 2 - White blood cells attack and destroy 3- Create memory cells |
| Benign Tumor | An abnormal, but usually harmless cell mass. |
| Heart Disease | Diseases and disorders that result from progressive damage to the heart and blood vessels. |
| Pathogen | Any agent that causes disease (aka germ) |
| Bacteria | Tiny, single-celled organisms, some of which can cause disease but many are helpful. |
| Virus | Smaller than bacteria and replicate only inside living cells. |
| Fungi | Organisms that absorb and use the nutrients of living or dead organisms. |
| Vaccine | A preparation of killed or weakened germ that is given (as by injection) to produce or increase immunity to a particular disease. |
| Heart Disease | Diseases and disorders that result from progressive damage to the heart and blood vessels. |
| Blood Pressure | The force the blood exerts against the inside walls of a blood vessel. |
| High Blood Pressure | High Blood Pressure |
| Symptom | A sign that a disease may be present |
| Hemorrhagic Stroke | Occurs when a blood vessel in your brain leaks or ruptures. Less common stroke. |
| Ischemic Stroke | Occur when the arteries to your brain become narrowed or blocked. Most common stroke. |
