  2. What will we study?? • How and why people get sick • Steps for diagnosing an infection • Applying Vitals (Review)

  3. Pathology

  4. Pathology (Key Terms) • Pathology - the study and diagnosis of disease through the examination of organs, tissues, bodily fluids and whole bodies (autopsy). • Disease– any condition that causes extreme pain, dysfunction, distress, social problems, and/or death

  5. Causes of Disease • 2 broad groups • (1) Infectious Diseases – can spread from one person to another and are caused by microscopic organisms called pathogens that invade the body. A microorganism’s disease-producing power is called its virulence. • Example: West Nile Virus

  6. Causes of Disease • 2 broad groups • (2) Non-infectious diseases – are not communicated from person to person and are not known to involve infectious agents. Some causes include: • Heredity • Lifestyle (diet, stress, etc.) • Example: Diabetes Type II

  7. Body’s Reaction to Disease • Immunity • The condition of being resistant to pathogens and the diseases they cause When these defenses are not functioning properly (poor health, bad nutrition…) people become particularly susceptible to invasion

  8. Body’s Reaction to Disease • When pathogens successfully invade the body, the immune system immediately begins to destroy them • The spleen, lymph nodes, tonsils, thymus, lungs, liver, kidneys and entire lymphatic system gets called into action • Lymphocytes • The specialized white blood cells responsible for combating infectious agents

  9. Do you ever feel like you always seem to get sick at the worst times?? Hmm, why do you think that is the case?
