Cada riñón presenta 2 caras y 2 extremidades o polos, pero difieren en forma y posición. Los riñones del equino carecen de lobulación. El riñón derecho, es triangular, se sitúa bajo las 2 ó 3 últimas costillas (16 ó 17 costillas) y la primera apófisis transversa lumbar (L1). La cara dorsal, es convexa y se relaciona con el diafragma, hígado y su porción posterior con los músculos Psoas Mayor y Menor. La cara ventral, es ligeramente cóncava y se relaciona con el hígado, páncreas, ciego y la adrenal derecha. Su borde medial, es convexo y redondeado. Cerca del centro de este borde, se encuentra el hilio renal que está limitado por bordes redondeados y conduce al seno renal que contiene a la pelvis renal u origen dilatado del uréter. Su extremidad anterior se adapta a la impresión renal del hígado. El riñón izquierdo, es más largo y estrecho que el riñón derecho, se sitúa por debajo de la última costilla (18 costilla) y las 2 a 3 primeras apófisis transversas lumbares (L2 y L3). La cara dorsal, es convexa y se relaciona con el pilar izquierdo del diafragma, la extremidad dorsal del bazo y los músculos Psoas mayor y Menor. Su cara ventral, es irregular y está relacionada con el origen del colon menor o colon flotante, la porción terminal del duodeno, la extremidad izquierda del páncreas y la adrenal izquierda. En el borde medial se observa el hilio renal y el borde lateral se relaciona con la base del bazo. Al realizar un corte del riñón encontramos que la parte central de la médula forma una cresta cóncava correspondiente a la cresta renal que se proyecta en el interior de la pelvis renal de manera infundibiliforme. Esta cresta presenta una superficie llamada área cribosa, la que está provista de numerosos orificios pequeños que corresponden a la desembocadura de los túbulos colectores renales. En realidad los túbulos colectores renales de cada extremidad del riñón no se abren en la pelvis renal propiamente dicha, sino en 2 divertículos largos y estrechos que se prolongan desde la pelvis hasta los polos del riñón. La irrigación renal, está dada por las arterias renales provenientes directamente de la Aorta, ramas de estas arterias penetran por el hilio, alcanzan la zona intermedia donde forman arcos anastomóticos (arterias arciformes), con ramas medulares y corticales (arterias interlobulillares) que emiten ramas laterales terminando en un corpúsculo renal (vaso aferente). En el hilio renal encontramos: vena renal, arteria renal, uréter, ganglios linfáticos y nervios. Los uréteres, comienzan en la pelvis y terminan en la cara dorsal de la vejiga urinaria. Tienen una porción abdominal que emerge ventrocaudalmente del hilio renal, se incurva caudomedialmente y se dirige en línea recta a la cavidad pélvica. La poción pelviana del uréter, se dirige caudoventralmente sobre la pared lateral de la cavidad pélvica, desciende y perfora la pared dorsal de la vejiga, cerca del cuello. La vejiga urinaria, se sitúa sobre la pared ventral de la cavidad pélvica y puede extenderse hacia la pared abdominal ventral, según el grado de repleción (llene) de la vejiga. Tiene una capacidad de 3 a 4 lts.. Consta de una extremidad anterior ciega (vértice o fondo) con el vestigio del uraco, una porción media (cuerpo) y una extremidad estrecha posterior (cuello) que se continúa con la uretra. La cara ventral se haya sobre el piso de la pelvis, la cara dorsal en el macho, se relaciona con el recto, pliegue genital, conductos deferentes, vesículas seminales y próstata. En la hembra se relaciona con el cuello del útero y con la vagina. Se fija a través de 3 pliegues peritoneales: 1 ligamento medio y 2 ligamentos laterales.</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"ÓRGANOS URINARIOS DEL EQUINO","attachmentId":53821292,"attachmentType":"pdf","work_url":"https://www.academia.edu/33839269/%C3%93RGANOS_URINARIOS_DEL_EQUINO","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/33839269/%C3%93RGANOS_URINARIOS_DEL_EQUINO"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="3" data-entity-id="25600088" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/25600088/ANATOM%C3%8DA_Y_FISIOLOG%C3%8DA_DEL_SISTEMA_URINARIO">ANATOMÍA Y FISIOLOGÍA DEL SISTEMA URINARIO</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="49209574" href="https://independent.academia.edu/SaudithArias">Saudith Arias</a></div><p class="ds-related-work--abstract ds2-5-body-sm">ANATOMÍA Y FISIOLOGÍA DEL SISTEMA URINARIO</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"ANATOMÍA Y FISIOLOGÍA DEL SISTEMA URINARIO","attachmentId":45930398,"attachmentType":"pdf","work_url":"https://www.academia.edu/25600088/ANATOM%C3%8DA_Y_FISIOLOG%C3%8DA_DEL_SISTEMA_URINARIO","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/25600088/ANATOM%C3%8DA_Y_FISIOLOG%C3%8DA_DEL_SISTEMA_URINARIO"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="4" data-entity-id="19522106" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/19522106/Sistema_urinario_humano">Sistema urinario humano</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="39814698" href="https://uteb.academia.edu/ALINASOLIS">ALINA SOLIS</a></div><p class="ds-related-work--abstract ds2-5-body-sm">El sistema urinario humano es un conjunto de órganos encargados de la producción de orina mediante la cual se eliminan los desechos nitrogenados del metabolismo (urea, creatinina y ácido úrico), y de la osmorregulación.
