Renal physiology (original) (raw)
La fisiología renal es el estudio de la fisiología de los riñones. La función principal del riñón es la regulación del medio interno mediante la excreción, de agua y metabolitos, así como la retención de que el organismo necesita; además, tiene una función endocrina secretando renina, calicreina, eritropoyetina y prostaglandinas.

| dbo:abstract | فيزيولوجيا الكلية أو وظائفية الكلية هي دراسة جميع وظائف الكلى، مثل إعادة امتصاص الجلوكوز والأحماض الأمينية ، والجزيئات الصغيرة الأخرى؛ تنظيم الصوديوم والبوتاسيوم والأملاح الأخرى ؛ تنظيم توازن السوائل وضغط الدم، والحفاظ على ، وإنتاج مختلف الهرمونات بما في ذلك إرثروبويتين، وتنشيط فيتامين د. تدرس فيزيولوجيا الكلية على مستوى النفرون، وهو أصغر وحدة وظيفية في الكلى. كل نفرون يبدأ بتركيب يعمل على تشريح الدم الداخل إلى الكلى. يتدفق هذا الرشح بعد ذلك بطول نفرون، وهو هيكل أنبوبي مبطن بطبقة واحدة من الخلايا المتخصصة المحاطة بالشعيرات الدموية. المهام الرئيسية لهذه الخلايا المبطنة هي إعادة امتصاص الماء والجزيئات الصغيرة من الرشح إلى الدم، وإفراز النفايات من الدم إلى البول. يتم التقييم الشامل لوظائف الكلى غالبا من خلال تقدير معدل الترشيح والذي يعرف (GFR). (ar) Gernu-aparatuaren fisiologia gernu-aparatuaren funtzionamenduaren azterketan datza. Aparatu horren eginkizun nagusiak zelulen katabolismoan sortzen diren hondakinak kanporatu eta gorputzaren barne-inguruaren homeostasia mantentzea da. Proteina eta base nitrogenatuen katabolismoan organismoarentzat toxikoak diren hainbat molekula sortzen dira: urea (proteinen katabolismoan), azido urikoa (base nitrogenatuen katabolismoan), NH3, gatz mineralak, etab. Gernu-aparatuak substantzia hauek odoletik kendu eta gernuaren bidez kanporatzen ditu. Gauza bera egiten du beharrezkoak diren baina odolean kontzentrazio handian dauden beste substantziekin: ura, ClNa.... Labur esanda, esan daiteke gernu-aparatuak odola garbitzen duela. Gernu-aparatuaren organo garrantzitsuenak giltzurrunak dira. Giltzurrunetan odol zikina garbitzen da eta dituen hondakin toxikoak bertan uzten dira, gernuaren bidez kanporatuak izateko. Giltzurrun-arteria giltzurrunetara iristen da hondakinez beteta. Arteria hori kapilar txikietan banatzen da, eta kapilar horiek giltzurrunen nefronetan sartzen dira. Bertan, hondakinak iragazi eta xurgatzen dira, eta baita ura ere. Hondakinak eta ura kanporatuak izaten dira gernuaren bidez eta odol garbia giltzurrun-zainetik irteten da.

(es) Renal physiology (Latin rēnēs, "kidneys") is the study of the physiology of the kidney. This encompasses all functions of the kidney, including maintenance of acid-base balance; regulation of fluid balance; regulation of sodium, potassium, and other electrolytes; clearance of toxins; absorption of glucose, amino acids, and other small molecules; regulation of blood pressure; production of various hormones, such as erythropoietin; and activation of vitamin D. Much of renal physiology is studied at the level of the nephron, the smallest functional unit of the kidney. Each nephron begins with a component that filters the blood entering the kidney. This filtrate then flows along the length of the nephron, which is a tubular structure lined by a single layer of specialized cells and surrounded by capillaries. The major functions of these lining cells are the reabsorption of water and small molecules from the filtrate into the blood, and the of wastes from the blood into the urine. Proper function of the kidney requires that it receives and adequately filters blood. This is performed at the microscopic level by many hundreds of thousands of filtration units called renal corpuscles, each of which is composed of a glomerulus and a Bowman's capsule. A global assessment of renal function is often ascertained by estimating the rate of filtration, called the glomerular filtration rate (GFR). (en) Fisiologia renal é o estudo da fisiologia dos rins. A unidade funcional do rim é o néfron. O sangue da arteríola aferente entra no glomérulo, onde parte é filtrado e parte sai do glomérulo pela arteríola eferente. O ultrafiltrado glomerular passa pelos túbulos do néfron, onde ocorre seu processamento através de reabsorção e secreção. Ao sair do Ducto coletor pelas papilas renais, entrando na pelve renal, o fluido já pode ser chamado de urina, já que as demais vias urinárias não processam o fluido. Este artigo foca na visão geral da fisiologia renal humana.
