Edema is a condition in which excess serous fluid accumulates in the body cavity or interstitial space of connective tissues. Edema is a sign observed in several medical conditions. Fluid dynamics in the body depend on body fluid compartments Body fluid compartments The adult human body is made up of 60% water and is divided into extracellular and intracellular fluid compartments. Extracellular fluid is present outside the cells and makes up two-thirds of the total body water. Intracellular fluid is present inside the cells and makes up two-thirds of the total body water. Body Fluid Compartments, fluid osmolarity Osmolarity The concentration of osmotically active particles in solution expressed in terms of osmoles of solute per liter of solution. Osmolality is expressed in terms of osmoles of solute per kilogram of solvent. Hypernatremia, and Starling forces Starling Forces Capillaries: Histology. Edema can be categorized into 2 types, namely, peripheral (in the extremities) and internal (in an organ or body cavity). Symptoms vary depending on location of the edema.
