    Study Notes

    Health, Sickness, and Prevention

    • Health involves physical, mental, and social well-being.
    • Disease is defined as an imbalance in the body's equilibrium, disrupting normal functioning.
    • Homeostasis is the state of equilibrium in the body needed to maintain life.
    • Glucose levels in the blood are regulated by insulin and glucagon.
    • Factors influencing disease and health include host factors (genetics, gender, age, immunity, nutrition, etc.), disease-causing agents (bacteria, viruses, etc.), and environmental factors.
    • Examples of disease-causing agents include viruses, bacteria, fungi, protozoa, and helminths.
    • Physical agents influencing disease include temperature changes, pressure of gases and liquids, mechanical effects, electricity, and radiation.
    • Chemical agents that can harm organisms include toxic substances (pesticides, metals) and nutritional element deficiencies (iodine, vitamin C, iron).

    Natural History of Disease and Levels of Prevention

    • Disease development follows a natural history, encompassing pre-pathogenic, pathogenic, and convalescence periods.
    • Environmental factors play a role in the pre-pathogenic period.
    • Disease-causing agents interact with a susceptible host.
    • The pathogenic period includes early pathogenesis (unobserved changes), clinical signs/symptoms, disease stage, and convalescence.
    • Disease can lead to recovery or chronic disease and sometimes death.
    • Prevention strategies are categorized as primary, secondary, and tertiary.
    • Primary prevention aims to prevent disease before it occurs.
    • Secondary prevention aims to detect and treat diseases early on.
    • Tertiary prevention involves managing the outcomes of illness or disease.

    The Immune System (1.3)

    • A human body is a complex conversation between cells.
    • The immune system defends against disease-causing agents.
    • Cells involved include specific cells that eat antigens and B cells (lymphocytes) that release antibodies.
    • The immune system helps maintain homeostasis.
