Liquide interstitiel 709613 31088653 2008-06-28T10:39:50Z Ginosbot 392252 robot Ajoute: [[lt:Audinių skystis]] {{ébauche|médecine}} Étant clair et liquide, le '''liquide interstitiel''' ou ''interstitium'' a une composition proche de celle du [[plasma sanguin]]. Le liquide interstitiel remplit l'espace entre les capillaires sanguins et les [[cellule (biologie)|cellules]]. Il facilite les échanges de nutriments et de déchets entre ceux-ci. Le surplus de liquide interstitiel est drainé par les [[système lymphatique|capillaires lymphatiques]] où il prend le nom de [[lymphe]] et est acheminé vers le cou où il est réintégré au sang dans la [[veine subclavière]] droite. <!-- '''Interstitial fluid''' is one of the two components of [[extracellular fluid]], the other being [[Blood plasma|plasma]]. On average, a person has about 11 liters (2.42 gallons) of interstitial fluid providing the cells of the body with nutrients and a means of waste removal. --> == Production et prélèvement == <!-- Plasma and interstitial fluid are essentially identical except for location. Plasma, the major component in blood, communicates freely with interstitial fluid through [[pore]]s and intercellular clefts in [[capillary]] [[endothelium]]. [[Blood pressure]] causes continuous production of interstitial fluid by pushing plasma through these openings into the [[interstitium]]. The pores are too small to allow [[protein]]s or cells through, but most other [[solute]]s can pass. Additionally, passive [[diffusion]] and [[active transport|active cellular transport]] from the blood also play a role in fluid production. Eventually, the interstitial fluid is forced back into the capillaries by osmotic pressure. Additionally, the fluid may drain into the [[lymphatic]] vessels. --> == Composition == <!-- Interstitial fluid consists of a water solvent containing [[amino acid]]s, [[sugar]]s, [[fatty acid]]s, [[coenzyme]]s, [[hormone]]s, [[neurotransmitter]]s, [[salt]]s, as well as waste products from the cells. --> == Fonction physiologique == <!-- Interstitial fluid bathes the [[cell (biology)|cells]] of the [[biological tissue|tissues]]. This provides a means of delivering materials to the cells, intercellular communication, as well as removal of metabolic waste. --> == Voir aussi == * [[Lymphe]] * [[Plasma sanguin]] == Références == *Marieb, Elaine N., Essentials of Human Anatomy & Physiology: Seventh Edition, San Francisco: Benjamin Cummings, 2003, ISBN 0-8053-5385-2. {{portail médecine}} [[Catégorie:Physiologie]] [[ar:سائل خلالي]] [[cs:Tkáňový mok]] [[da:Interstitialvæske]] [[de:Gewebsflüssigkeit]] [[en:Interstitial fluid]] [[es:Líquido intersticial]] [[fi:Kudosneste]] [[ja:間質液]] [[lt:Audinių skystis]] [[pt:Fluido intersticial]]
