Renal portal system. A renal portal system is a portal venous system found in reptiles, and fish excluding hagfish and lampreys. It is not found in mammals. [1] Its function is to supply blood to renal tubules when glomerular filtration is absent or downregulated. [2]
Introduction. Anatomy (from Ancient Greek ἀνατομή (anatomḗ) ' dissection ') is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science that deals with the structural organization of living things. It is an old science, having its beginnings in prehistoric times.
In contrast, systemic anatomy is the study of the structures that make up a discrete body system—that is, a group of structures that work together to perform a unique body function, such as the digestive system. Anatomy can be studied using both invasive and non-invasive methods with the goal of obtaining information about the structure and ...
Capillaries join the arteries and veins. The circulatory system is a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of a human or other vertebrate. [1] [2] It includes the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia ...
The system anatomy can be used as a starting point when creating an integration anatomy (aka project anatomy) that has more use as a project management tool. Example. The following example is a simplified example of a system anatomy for an issue management system. This anatomy is drawn with the most basic capabilities at the top.
Superior and inferior duodenal fossæ. In human anatomy, the inferior mesenteric vein ( IMV) is a blood vessel that drains blood from the large intestine. It usually terminates when reaching the splenic vein, which goes on to form the portal vein with the superior mesenteric vein (SMV).
Splenic vein. The splenic vein, here called the "lienal vein", travels from the spleen, above the pancreas, and ends in the portal vein. In human anatomy, the splenic vein (formerly the lienal vein) is a blood vessel that drains blood from the spleen, the stomach fundus and part of the pancreas. It is part of the hepatic portal system .
The biliary tract (also biliary tree or biliary system) refers to the liver, gallbladder and bile ducts, and how they work together to make, store and secrete bile. [1] Bile consists of water, electrolytes, bile acids, cholesterol, phospholipids and conjugated bilirubin. [2] Some components are synthesized by hepatocytes (liver cells); the rest ...
