In lungfish and tetrapods, the renal portal vein is joined by a vein traveling upwards from the abdominal vein, which can bring venous blood from the hind limbs and ventral body wall into the renal portal system, or alternatively, enable blood from the tail and groin to pass into the hepatic portal system, already served by blood from the gut, via the hepatic portal vein, and from the hind ...
The human hepatic portal system delivers about three-fourths of the blood going to the liver.The final common pathway for transport of venous blood from spleen, pancreas, gallbladder and the abdominal portion of the gastrointestinal tract (with the exception of the inferior part of the anal canal and sigmoid colon) is through the hepatic portal vein.
Anatomical terminology. [ edit on Wikidata] The renal circulation supplies the blood to the kidneys via the renal arteries, left and right, which branch directly from the abdominal aorta. Despite their relatively small size, the kidneys receive approximately 20% of the cardiac output. [1]
Kidney. In humans, the kidneys are two reddish-brown bean-shaped blood-filtering organs [1] that are a multilobar, multipapillary form of mammalian kidneys, usually without signs of external lobulation. [2] [3] They are located on the left and right in the retroperitoneal space, and in adult humans are about 12 centimetres ( 41⁄2 inches) in ...
It is a major component of the hepatic portal system, one of three portal venous systems in the human body; the others being the hypophyseal and renal portal systems. The portal vein is usually formed by the confluence of the superior mesenteric, splenic veins, inferior mesenteric, left, right gastric veins and the pancreatic vein.
The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites, and regulate blood pH. The urinary tract is the body's drainage system for the eventual removal of urine. [1] The kidneys have an extensive blood supply via the renal arteries which ...
Abdomen. Anatomical terminology. [ edit on Wikidata] In human anatomy, the hepatic portal system or portal venous system is the system of veins comprising the portal vein and its tributaries. The other portal venous system in the body is the hypophyseal portal system. [1]
Renal physiology. This illustration demonstrates the normal kidney physiology, including the Proximal Convoluted Tubule (PCT), Loop of Henle, and Distal Convoluted Tubule (DCT). It also includes illustrations showing where some types of diuretics act, and what they do. Renal physiology ( Latin rēnēs, "kidneys") is the study of the physiology ...
