Most portal circulations consist of two serial capillary beds connected by one or more larger vessels. We have called these ‘convergent’ portal circulations: examples are hepatic portal, placental, hypophysial, renal, ovarian and testicular circulations, as are parts of the lymphatic circulation. A second type of portal circulation, which is less common, consists of two serial capillary beds that are not connected by larger vessels.Author: Publish Year:

What is portal circulation in vertebrates? circulatory system Lower vertebrates have two so-called portal systems, areas of the venous system that begin in capillaries in tissues and join to form veins, which divide to produce another capillary network en route to the heart. What are the different types of portal circulation?
What is hepatic portal circulation? 1. Circulation of blood to the liver from the small intestine, the right half of the colon, and the spleen through the portal vein; sometimes specified as the hepatic portal circulation. 2.

What is the meaning of portal circulation? Definition of a portal circulation: An arrangement by which blood collected from one set of capillaries passes through a large vessel or vessels, to another set of capillaries before returning to the systemic circulation. Portal Systems in Human Circulation. System.
What is a portal circulation? This circulation of nutrient-rich blood between the gut and liver is called the portal circulation. It enables the liver to remove any harmful substances that may have been digested before the blood enters the main blood circulation around the body—the systemic circulation.
What is the function of the hepatic portal circulation? Things to Remember:
- The Portal system is the system where the veins of the body begin.
- It supplies the deoxygenated blood to the liver to purify the blood before it is transported to the heart.
- It is the venous system that includes the hepatic portal vein and its tributaries.

What is portal system? Portal system can be defined as a part of the systemic circulation, in which blood draining from the capillary bed of one structure flows through larger vessels to supply the capillary bed of another structure, before returning to the heart. Simply, a system of blood vessels that begins and ends in capillaries is called portal system.
