  4. 4. Terms Used In Pathophysiology • Pathology = study of disease (Pathology is a result of disease and changes in homeostasis). • Pathogenesis = the development of a disease(A. The development of a disease is referred to as pathogenesis (-genesis = origin or development). Example: common cold 1. Cause = exposure and inoculation of cold virus 2. Incubation time = virus multiplies 3. Manifestation = host begins to have signs and symptoms (sore throat, itchy eyes, runny nose, etc.) 4. Recovery = return to previous state of health

  6. 6. Predisposing Factors (risk factors) • Age • Young are prone to accidents • Getting diseases such as diabetes, heart disease, and certain cancers increase with age • Very old are prone to drug interactions • Sex • More frequent in woman: MS, osteoporosis • More frequent in men: gout, Parkinson’s disease • Lifestyle • Examples of harmful lifestyle: » Perilous occupation » Smoking » Excess alcohol » Poor nutrition » Sedentary activity
