Chapter 1 - Mechanisms Of Disease, Diagnosis, And Treatment Flashcards
Homeostasis
internal stability of the body
Pathologic conditions involve
measurable
changes in normal structure and function
Pathogenesis
Development of disease in stages
Pathogenesis of the common cold
- Incubation - No signed yet evident
- Entry into the body
- Full-blown illness
- Recovery
Systemic health
Internal equilibrium
Disease state
Inability to adapt to internal and External stressors
Syndrome

Diagnosis
Identifying or naming the disease or condition
Prognosis
Predicted or expected outcome. for example a common cold to last 7 to 10 days
Treatment
Plan of care. Ex) Medication, surgery, etc
Benign tumors characteristics
◦ Develop and grow very slowly ◦ Can arise from any tissue ◦ Usually remain encapsulated (self-contained) ◦ Cells are well differentiated ◦ Usually not life threatening ◦ Rarely recur after surgical removal
Malignant tumors characteristics
◦ Cells multiply rapidly
◦ Do not usually resemble the tissue of origin
(undifferentiated)
◦ Invade surrounding tissue
◦ Often recurrent
◦ Infiltrate to distant sites (metastasize)
Cancer treatment
◦ Surgery ◦ Radiation ◦ Chemotherapy ◦ Hormone therapy ◦ Immunotherapy ◦ Palliative surgery
