KINE 250 Lecture Notes - Lecture 7: Common Cold, Immunodeficiency, Antigen
Document Summary
Many illnesses are thought to be caused or aggravated by stress. Long term exposure to stress depletes energy needed for re-growth and repair. Most well-known symptom for mumps: swollen salivary glands. Swine (pig) flu a (h1n1): contains combined elements of a human flu virus and the pig virus. Found in air and food; on nearly every object or person. Virulent pathogen: strong enough to overcome host resistance and cause disease. Epidemic: disease outbreak that affects many people in a community or region at the same time. Endemic: always present; can never be eradicated (i. e. common cold) Causes: not enough sleep, poor diet, etc. Autoinoculation: transmitting a pathogen from one part of your body to another. Animal-borne: spread by domestic and wild animals. Antigens: anything that produces an immune response. Body produces lymphocytes (macrophages; b cells; t cells) Destroy antigens after antibodies attach to them. B cells: produce antibodies that attach to antigens. Killer t cells: kill antigens in system.
