Anatomy of the Liver The blood supply of the liver is unique among all organs of the body due to the hepatic portal vein system. Blood traveling to the spleen, stomach, pancreas, gallbladder, and intestines passes through capillaries in these organs and is collected into the hepatic portal vein.

Hepatic Portal System Hepatic Portal System. carries venous blood from the digestive organs to the liver via portal vein; nutrient rich DOB absorbed from the GI tract is processed in the liver before entering the heart; is unique because it has capillary beds on both ends.

Human Physiology/Print Version Hepatic veins are unusual in that they do not have valves. Hepatic veins are blood vessels which transport the liver's deoxygenated blood and blood which has been filtered by the liver (this is blood from the pancreas, colon, small intestine, and stomach) to the inferior vena cava.

Hepatic Portal Vein Human Anatomy » Body Systems » Cardiovascular System » Hepatic Portal Vein. The hepatic portal vein is a component of the hepatic portal system of human body. By definition, the hepatic portal vein drains deoxygenated, but nutrient rich blood from different organs to the liver. Thus it is not a true vein, which by definition should drain the deoxygenated blood into the heart.

Human Physiology/Print Version Hepatic Veins. Hepatic veins are blood vessels which transport the liver's deoxygenated blood and blood which has been filtered by the liver (this is blood from the pancreas, colon, small intestine, and stomach) to the inferior vena cava. The hepatic veins originate in the liver lobule's central vein.

Hepatic Portal System venous route that drains blood from the spleen and pancreas into the hepatic portal vein; unites with the superior mesenteric vein to for the hepatic portal vein. Hepatic portal vein. a vein connecting the capillary bed of the intestines with the capillary bed of the liver. This allows amino acids and glucose absorbed from the intestines to be delivered first to the liver for processing before being transported throughout the circulatory system.

What factors affect circulation of blood in the heart? Capillary circulation is the part of your overall blood circulatory system where oxygen, nutrients, and waste pass between your blood and parts of your body. Capillaries connect the arterial and venous circulatory subsystems. Capillaries are very small blood vessels.

Blood Supply to the Liver and Gallbladder The liver is unique among organs in that it receives blood via two distinct circulatory routes: systemic circulation and hepatic portal circulation. Each of these routes provides blood of differing compositions that allow the liver to perform its unique and vital digestive and metabolic functions.

Circulatory System The largest capillaries are found in the liver. (capillar comes from the greek for hairlike). Capillaries connect arterioles to venules. They allow the exchange of nutrients and wastes between the blood and the tissue cells, together with the interstitital fluid.This exchange occurs by passive diffusion and by pinocytosis which means 'cell drinking'. Pinocytosis is used for proteins, and some lipids.hey allow the exchange of nutrients and wastes between the blood and the tissue cells, together with the interstitital fluid.

Anatomy Lesson 11 Circulatory System Capillaries are minute blood vessels that join onto the arterioles. They are one cell thick and are exchange points where the nutrients (oxygen and glycogen) cross into the tissue cells (muscles) from the arterioles.

Lymphatic System Anatomy The lymphatic system parallels the cardiovascular system (see the images below). The lymphatic system is unique, in that it is a 1-way system that returns lymph fluid via vessels to the cardiovascular system for eventual elimination of toxic byproducts by end organs, such as the kidney, liver, colon, skin, and lungs. Lymph nodes and vessels, anterior view. Lymphatic system, anterior view. Table 1.

- A capillary is an extremely small blood vessel located within the tissues of the body, that transports blood from arteries to veins. Capillaries are most abundant in tissues and organs that are metabolically active.apillary Size. Capillaries are so small that red blood cells can only travel through them in single file. Capillaries measure in size from about 5-10 microns in diameter. Capillary walls are thin and are composed of endothelium (a type of simple squamous epithelial tissue).

Capillary Capillary: Capillary, in human physiology, any of the minute blood vessels that form networks throughout the bodily tissues; it is through the capillaries that oxygen, nutrients, and wastes are exchanged between the blood and the tissues. The capillary networks are the ultimate destination of arterial blood

Lymph capillary From Wikipedia, the free encyclopedia. Lymph capillaries or lymphatic capillaries are tiny, thin-walled vessels located in the spaces between cells (except in the central nervous system and non-vascular tissues) which serve to drain and process extra-cellular fluid.rom Wikipedia, the free encyclopedia.

portal circulation portal system an arrangement by which blood collected from one set of capillaries passes through a large vessel or vessels and another set of capillaries before returning to the systemic circulation, as in the pituitary gland (the hypothalamo-hypophysial portal system) or the liver (the hepatic portal circulation).

Anatomy of the Liver Most of the bile produced by the liver is pushed back up the cystic duct by peristalsis to arrive in the gallbladder for storage, until it is needed for digestion. Blood Vessels.

Blood traveling to the spleen, stomach, pancreas, gallbladder, and intestines passes through capillaries in these organs and is collected into the hepatic portal vein.

Where Is Your Liver and What Does It Do? All blood from the liver is drained by the hepatic veins into the inferior vena cava. Lymph is drained from the liver by lymphatic vessels of the liver, which include superficial and deep lymphatic vessels. Hepatic lymph nodes are found along the hepatic vessels and the lesser omentum.

Toxic Substances Portal The heart and blood vessels (arteries, capillaries, and veins) are called the cardiovascular system. The cardiovascular system carries blood throughout the body. The heart pumps blood through blood vessels called arteries and then through smaller blood vessels called capillaries to each organ and tissue in the body.
