Why the hepatic blood carried to the liver before it enters the systemic circulation?

Hepatocytes destroy harmful chemicals that are present in the blood. The liver's macrophages remove bacteria and other debris from the passing blood which allows proper maintenance of sugar, fatty acids & amino acid concentration in the blood.
The liver is the key body organ involved in maintaining proper sugar, fatty acid, and amino acid concentration in the blood, and this system ensures that these substances pass through the liver before entering the systemic circulation. As blood percolates through the liver sinusoid's, some of the nutrients are removed to be stored or processed in various ways for release to the general circulation. At the same time, the hepatocytes are detoxifying alcohol and other possibly harmful chemicals present in the blood, and the liver's macrophages are removing bacteria and other debris from the passing blood.

∙ 9y agoThe hepatic portal system blood is carried to the liver before it enters the systemic circulation for nutrients to be processed. The blood carried here is nutrients which are extracted and toxins are also filtered.
Wiki User
∙ 14y agoThe blood is carried in to the liver by hepatic portal vein, in order to fix the essential nutrients that have obtained by the digestion of food materials. Then it enters the systemic circulation. This process only gives us energy to survive. And this system is known as Hepatic Portal System.

∙ 9y agoThe portal vein is no real vein because blood carries capillary beds in the liver and not directly to the heart. It is an important part of the hepatic portal system, one of only two portal venous systems in the body - the pituitary portal vein which are different.

∙ 14y agoThe portal system carries blood from the intestines to the liver. Intestinal blood goes to the liver first because it is full of nutrients that the liver can use (most importantly glucose that the liver can turn into glycogen). Also, any ingested toxins get shunted to the liver first, which is also great because the liver has enzymes that can detoxify things before they get into the systemic circulation.

Why does the hepatic vein contain more glucose before eating?
After eating, glucose is greater in the hepatic portal vein than in the hepatic vein . Hepatic vein contain more glucose before eating, because the stomach is empty .
Why the lungs are largely bypassed by the circulating blood in the fetus?
It doesnt, the echange surfaces of the lungs get their very own circulaiton in the pulmonary circulation. The nonexchange surfaces in the lungs (the bronchi etc) are supplied with oxgen and nutrients in the systemic circulation.
The liver is the first stop for most absorbed nutrients because it?
Because the hepatic portal vein carried blood directly from the small intestine to the liver before going to the heart. Meaning the liver gets all the nutrients in it directly.
What is prehepatic Jaundice and posthepatic jaundice?
Jaundice is a condition where the skin turns yellow because of excess bilirubin in the bloodstream. It happens when your liver is not functioning properly, which can be due to a number of factors. Hepatitis is a virus which can cause liver disease, and thus cause Jaundice.
Which vessels contain the most glucose before eating?
The Hepatic Portal Vein
What are the two types of blood circulation and explain each type?
Systemic Circulation - Oxygenated blood is pumped from the left ventricle of the heart heart to the entire body (except the lungs) through the aorta and deoxygenated blood is drained back to the right atrium of the heart through the vena cavae. Pulmonary Circulation - Deoxygenated blood is pumped from the right ventricle of the heart to the lungs through the pulmonary trunk, and oxygenated blood flows back to the left atrium of the heart through the pulmonary veins.
What is the hepatic system?
The hepatic (portal) system refers to the blood vessels that carry blood from the intestines, stomach, pancreas and spleen to the liver. Blood containing nutrients or drugs absorbed from the intestine is transported by the hepatic portal system to the liver for metabolism before distribution to the rest of the body.
What is the main purpose of the hepatic-portal circulation?
Hepatic Portal Circulation The veins of the hepatic portal circulation drain the digestive organs, spleen, and pancreas and deliver the blood to the liver via hepatic portal vein. As blood percolates through the liver, some of the nutrients are stored or processed in various ways for release to the general circulation. The liver in turn is drained by the hepatic veins that enter the inferior vena cava. The inferior mesenteric vein, draining the distal part of the large intestine, joins the splenic vein, which drains the spleen, pancreas and stomach. The splenic vein and the superior meseteric vein, which drains the small intestine and the proximal colon, unite to form the hepatic portal vein. The left gastric vein, which drains the lesser curvature of the stomach, drains directly into the hepatic portal vein.

What advantages are there in supplying pulmonary circulation with blood at low pressure than that of systemic circulation?
Because the pulmonary circuit only pumps blood to the lungs and back to oxygenate it before it is sent round the rest of the body. The Systemic circuit must pump the blood everywhere else in the body and therefore has a much larger distance to cover which is why it needs more force and pressure.
