Edema (American English), or œdema (British English), formerly known as dropsy or hydropsy, is the increase of interstitial fluid in any organ — swelling. Phonology North American English regional phonology In many ways compared to English English, North American English is conservative in its Phonology. British English or UK English ( BrE, BE, en-GB) is the broad term used to distinguish the forms of the English language used in the Interstitial fluid (or tissue fluid) is a solution which bathes and surrounds the cells of multicellular animals Generally, the amount of interstitial fluid is determined by the balance of fluid homeostasis, and increased secretion of fluid into the interstitium or impaired removal of this fluid may cause edema. Homeostasis (from Greek: ὅμος hómos, "equal" and ιστημι istēmi, "to stand" lit
Edema has five pathophysiologic causes. It can be due to increased hydrostatic pressure, reduced oncotic pressure, lymphatic obstruction, sodium retention, or inflammation. Fluid statics (also called hydrostatics) is the Science of Fluids at rest and is a sub-field within Fluid mechanics. Oncotic pressure in the Circulatory system is a form of Osmotic pressure exerted by Proteins in Blood plasma that normally tends to pull The lymphatic system in Vertebrates is a network of conduits that carry a clear fluid called Lymph. Sodium (ˈsoʊdiəm is an element which has the symbol Na( Latin natrium, from Arabic natrun) atomic number 11 atomic mass 22 Inflammation ( Latin, inflamatio, to set on fire is the complex biological response of vascular tissues to harmful stimuli such as Pathogens [1]

Generation of interstitial fluid is regulated by the Starling equation of tissue fluid which states that it depends on the balance of osmotic pressure and of hydrostatic pressure which act in opposite directions across the semipermeable capillary walls. The Starling equation is an equation that illustrates the role of hydrostatic and oncotic forces (the so-called Starling forces) in the movement of fluid Osmotic pressure is the hydrostatic pressure produced by a difference in concentration between solutions on the two sides of a surface such as a semipermeable membrane Fluid statics (also called hydrostatics) is the Science of Fluids at rest and is a sub-field within Fluid mechanics. A semipermeable membrane, also termed a selectively-permeable membrane, a partially-permeable membrane or a differentially-permeable membrane, is a membrane Capillaries are the smallest of a body's Blood vessels measuring 5-10 μm in diameter which connect Arterioles and Venules and enable the interchange Consequently, anything that increases oncotic pressure outside blood vessels (for example inflammation), or reduces oncotic pressure in the blood (states of low plasma osmolality, for example, cirrhosis) will cause edema. Inflammation ( Latin, inflamatio, to set on fire is the complex biological response of vascular tissues to harmful stimuli such as Pathogens Oncotic pressure in the Circulatory system is a form of Osmotic pressure exerted by Proteins in Blood plasma that normally tends to pull Blood plasma is the Liquid component of Blood, in which the Blood cells are suspended Osmolarity is a measure of the osmoles of solute per Liter of solution while the osmolality is a measure of the osmoles of Solute per Kilogram Cirrhosis is a consequence of chronic Liver Disease characterized by replacement of liver tissue by fibrous Scar tissue as well as regenerative Increased hydrostatic pressure inside the blood vessel (for example in heart failure) will have the same effect. Fluid pressure is the Pressure at some point within a Fluid, such as water or air Heart failure is a Cardiac condition that occurs when a problem with the structure or function of the Heart impairs its ability to supply If the permeability of the capillary walls increases, more fluid will tend to escape out of the capillary, as can happen when there is inflammation. Inflammation ( Latin, inflamatio, to set on fire is the complex biological response of vascular tissues to harmful stimuli such as Pathogens
Abnormal removal of interstitial fluid is caused by obstruction of the lymphatic system, for example due to pressure from a cancer or enlarged lymph nodes, destruction of lymph vessels by radiotherapy, or infiltration of the lymphatics by infection such as elephantiasis. The lymphatic system in Vertebrates is a network of conduits that carry a clear fluid called Lymph. Cancer (medical term Malignant Neoplasm) is a class of Diseases in which a group of cells display uncontrolled A Lymph node ( lɪmf noʊd is an organ consisting of many types of cells and is a part of the Lymphatic system. Radiation therapy (or radiotherapy) is the medical use of Ionizing radiation as part of Cancer treatment to control Malignant Elephantiasis (/ˌɛləfənˈtaɪəsɪs -fæn-/ -fan- is a disease that is characterized by the thickening of the skin and underlying tissues especially in the legs and genitals
There are two types: exudate and transudate
Edema of specific organs (cerebral edema, pulmonary edema, macular edema) may also occur, each with different specific causes to peripheral edema, but all based on the same principles. An exudate is any Fluid that filters from the Circulatory system into Lesions or areas of Inflammation. Transudate is extravascular fluid with low protein content and a Specific gravity Cerebral edema (cerebral oedema in British English) is an excess accumulation of water in the intracellular and/or extracellular spaces of the Brain. Pulmonary Edema (American English or oedema (British English is swelling and/or fluid accumulation in the Lungs It leads to impaired gas exchange and may cause Macular Edema occurs when fluid and Protein deposits collect on or under the Macula of the Eye, a yellow central area of the Retina Ascites is effectively edema within the peritoneal cavity, as pleural effusions are effectively edema in the pleural cavity. In Medicine ( Gastroenterology) ascites (also known as peritoneal cavity fluid, peritoneal fluid excess, hydroperitoneum or more In higher Vertebrates the peritoneum is the Serous membrane that forms the lining of the abdominal cavity &mdash it covers most of the intra-abdominal Pleural effusion is excess fluid that accumulates in the Pleural cavity, the fluid-filled space that surrounds the Lungs Excessive amounts of such fluid can impair Causes of edema which are generalized to the whole body can cause edema in multiple organs and peripherally. For example, severe heart failure can cause peripheral edema, pulmonary edema, pleural effusions and ascites.
Common and usually harmless appearances of cutaneous edema are observed with mosquito bites and skin contact with certain plants (urticaria). Mosquitoes are insects in the family Culicidae. They have a pair of scaled wings a pair of Halteres, a slender body and long legs
Edema may be found in the eyes after corrective surgery or procedures of that nature.
Edema in plants is the extended swelling in plant organs caused primarily by an excessive accumulation of water since the cell wall is composed of flexible cellulose.
