  • See page 60 of text: malaria Autosomal recessive hereditary disease Description and etiology is the medical classification Signs/symptoms/lab values are the distinguishing features
  • Pathogens include bacteria, fungi, worms, protozoa, parasites, viruses Trauma = injury or wound caused by external force Physical & Chemical agents=extreme temperature, radiation, atmospheric pressure, electric shock, poisoning, drowning, bites, asphyxiation, burns Genetic= neoplasm, mutations, autosomal dominant/recessive Metabolic or nutritional= malnourish, vitamin and mineral deficiency or excesses Ask students for 3 examples of disease for each category
  • Example: malaria Risk of death, medication resistance, weakness due to anemia, jaundice (liver problems, fatigue) Illness experience includes: Onset – 1 st symptoms appear Diagnosis – identification of disease/condition Patient status – how patient adjusts to the condition Recovery – may not be “all better”
  • Local venules, arterioles, and capillaries dilate causing blood flow to injured area (causing heat and redness) As the blood flow increases, more leukocytes reach the area, lining up within the capillary walls The damaged cells release histamine, causing …. Increased permeability of the capillary walls allowing plasma and neutrophils to leave the blood vessels and into the surrounding tissue Swelling (edema) puts pressure on sensitive nerve endings causing pain and tenderness Pain and tenderness causes loss of function Factors that reduce the inflammatory response are adequate nutrition, rest, good blood supply
  • Natural immunity through genetic makeup, normal body structure Acquired – defense of recognized, specific antigen by antibodies
  • Anaphylaxis: severe allergic reaction usually life threatening. Acute May occur after single or multiple exposures. Can occur within seconds or 40-50 minutes later Ask students if they have allergies, what are their symptoms.
  • Transcript

    • 1. The Disease Process Objectives
      • Define disease
      • Define illness
      • Identify the process of inflammation
      • Identify 3 means of protection provided by the immune system
      • Identify allergic reaction
    • 2. Define disease
      • Pathological condition of the body in response to alteration in normal body harmony: disruption of homeostasis
      • Known by medical classification and distinguishing features
    • 3. Disease Result of:
      • Pathogens
      • Trauma
      • Physical and chemical agents
      • Genetics
      • Metabolic or nutritional disorders
    • 4. Define Illness
      • Describes the condition of a person who is experiencing disease; how they feel, what they think about disease and how it will affect their lives
    • 5. Identify Process of Inflammation
      • Redness
      • Swelling
      • Pain
      • Heat
      • Loss of Function
    • 6. 3 Means of Protection by Immune System
      • Normal body structures block entry of pathogens (skin, mucous membranes)
      • Inflammatory response (pathogens identified as foreign, or allergen) engulfed by phagocytosis
      • Specific immune response (through natural or acquired immunity)
    • 7. Identify allergic reaction
      • Occurs when immunity malfunctions
      • Predisposing factors include family history, stress, physical condition
