Is edema intracellular or extracellular?
extracellular fluid
Edema refers to the presence of excess fluid in the body tissues. In most instances, edema occurs mainly in the extracellular fluid compartment, but it can involve intracellular fluid as well.
Is edema interstitial fluid?
Edema is defined as a palpable swelling produced by expansion of the interstitial fluid volume; when massive and generalized, the excess fluid accumulation is called anasarca.
What is the fluid in edema?
Edema occurs when tiny blood vessels in your body (capillaries) leak fluid. The fluid builds up in surrounding tissues, leading to swelling. Mild cases of edema may result from: Sitting or staying in one position for too long. Eating too much salty food.
Is edema in the ICF or ECF?
ECF compartment
-Edema occurs mainly in the ECF compartment Normally, fluid is constantly moving in & out of the interstitial space to allow ECF to distribute between plasma and IF (Through capillary walls).
What causes intracellular edema?
Impairment of energy metabolism caused by hypoxia leads to intracellular oedema, because Na+ accumulates in the cells when ATP is no longer available for the sodium pump.
Does edema cause increased capillary refill?
The accumulation of fluid occurs when local or systemic conditions disrupt this equilibrium, leading to increased capillary hydrostatic pressure, increased plasma volume, decreased plasma oncotic pressure (hypoalbuminemia), increased capillary permeability, or lymphatic obstruction.
How edema is formed?
Edema occurs when an excessive volume of fluid accumulates in the tissues, either within cells (cellular edema) or within the collagen-mucopolysaccharide matrix distributed in the interstitial spaces (interstitial edema) [14,42,62,64,87,88,141,215,247,279].
How is edema formed?
Edema is the clinical manifestation of an accumulation of fluid within the interstitial spaces of the body. It develops when the normal balance between the flow of fluid out of capillaries and the return of fluid to the vascular space via capillary reabsorption and lymphatic flow is disrupted.
Is dehydration intracellular or extracellular?
In dehydration, fluid from the extracellular compartment is depleted first, followed by fluid from the intracellular space. Fluid loss from the intracellular space results in cellular shrinkage and metabolic dysfunction. Dehydration occurs because of decreased water intake, increased fluid loss, or both.
What causes rapid capillary refill?
A prolonged capillary refill time may be a sign of shock and can also indicate dehydration and may be a sign of dengue hemorrhagic fever and decreased peripheral perfusion. Prolonged capillary refill time may also suggest peripheral artery disease.
What causes extracellular edema?
Edema is an abnormal accumulation of extracellular water resulting from malfunction of the physiologic mechanisms that regulate total body water, circulating intravascular volume, and the maintenance of cellular and extracellular electrolytes in the appropriate concentrations.
What is extracellular fluid called?
The extracellular fluid (or interstitial fluid) bathing the cells of the brain and spinal cord is cerebrospinal fluid, which contains the same chemical ions and a much higher concentration of water than the intracellular fluid.
What is the pathophysiology of Extracellular edema?
Extracellular fluid edema occurs when there is excess fluid accumulation in the extracellular spaces. There are two general causes of extracellular edema: (1) abnormal leakage of fluid from the plasma to the interstitial spaces across the capillaries, and (2) failure of the lymphatics to return fluid from the interstitium back into the blood.
What is edema and what causes edema?
Edema refers to the presence of excess fluid in the body tissues. In most instances, edema occurs mainly in the extracellular fluid compartment, but it can involve intracellular fluid as well. Edema refers to the presence of excess fluid in the body tissues.
What is excess fluid in the tissue called?
Edema: Excess Fluid in the Tissues. Edema refers to the presence of excess fluid in the body tissues. In most instances, edema occurs mainly in the extracellular fluid compartment, but it can involve intracellular fluid as well. Edema refers to the presence of excess fluid in the body tissues.
What is the difference between inflammation and fluid edema?
Inflammation usually has a direct effect on the cell membranes to increase their permeability, allow-ing sodium and other ions to diffuse into the interior of the cell, with subsequent osmosis of water into the cells. Extracellular fluid edema occurs when there is excess fluid accumulation in the extracellular spaces.
