LEARNING OBJECTIVES: K & U GENERAL FEATURES  - NORMAL FLUID COMPARTMENTS.  EDEMA: --- PATHOGENESIS --- ASSOCIATED DISEASES  HYPEREMIA AND CONGESTION  HEMORRHAGE: HEMATOMA, PETECHIA, PURPURA, ECCHYMOSIS, CAVITIES ACCUMULATIONS. MEDICAL SIGNIFICANCE!!! Ref: pp. 119-124 & lecture’s information 

Hemodynamic Disorders Normal regulation of fluid movement

Extravascular fluid (little protein or pressure)

Hydrostatic

Oncotic

pressure

pressure

HEMODYNAMIC DISORDERS. PATHOGENESIS OF EDEMA:     

INCREASED HYDROSTATIC P. REDUCED OSMOTIC P. LYMPHATIC OBSTRUCTION. SODIUM RETENTION. INFLAMMATION.

Non-Inflammatory Edema Increased Hydrostatic Pressure

EDEMA -TRANSUDATE (protein content low - specific gravity <1.012)
