OTHER DISEASE CAUSING FACTORS

4 DAYS LEFT…YOU THINK IT’S TIME TO START STUDYING?

Toxins

• CO2 is a “naturally produced” toxin• Arsenic in ground water in India• Ricin– 1 mg of ricin can kill a human

Genetics

• Genes: heredity material passed from parents to offspring

• Non-communicable diseases– Cannot be passed from one person to another

through contact or proximity– Ex:• Diabetes, hypertension, cystic fibrosis, PKU,

hemophilia, sickle cell, red green color blindness, etc

Immune Response

• Pathogen enters the body• Histamine is released– Histamines cause inflammation (swelling)– Fluids build up to localize infection– Blood flow increases– White blood cells are signaled– Inflammation response also associated with

creating a fever

Immune Response• White blood cells travel to site to digest

pathogen (antigen)– Antigen is a “foreign substance” in the body

• Digestion of pathogen signals presence of antigen

• Antibodies form against antigens– T-Cells: recognize an antigen (pathogen)• Some T-Cells will attack the infected cells• Other T-Cells activate “B-Cells” to produce antibodies

that will destroy the pathogen

Immune Response• T-Cells and B-Cells are “White Blood Cells”• Antibodies are “Antigen Specific”

• Measles antibody will only bind with measles antigen

• After antibodies are produced, immunity develops to the pathogen– The ability to resist disease– can be two types of immunity• Active Immunity• Passive Immunity

Immune Response• Active Immunity– Acquired when an immune response is activated

by the body– Long term immunity

• Passive Immunity– When antibodies are introduced into the body– When mothers transfer antibodies to an infant

through breast-feeding– Short term immunity

Healthy Nutrition

• People who make healthy life choices often avoid chronic or age related diseases– Healthy diets, exercise, etc– Others listed on page 218 of PTNCEOC green book

• Nutrients– Substances needed by an organism to carry out

life functions• Carbs, fats, proteins, nucleic acids, vitamins and

minerals (Eat Yo’ Wheaties)
