The hepatic portal system is an essential part of the human circulatory system. Understanding how it works can also help you in improving your understanding of human anatomy in general. The hepatic portal system consists of numerous veins and tributaries, including the hepatic portal vein. While the hepatic portal system is also often referred to as the portal venous system, it is important to note that there are also other venous systems in the human body that are also referred to as portal venous systems.

Hepatic Portal System

The hepatic portal system is one of many primary components of the circulatory system that can be found in the abdominal cavity. The hepatic portal vein is one of the largest veins in the area and it carries blood to liver from the spleen and the gastrointestinal tract. The hepatic vein begins where the splenic veins and the superior mesenteric meet. The hepatic vein also drains blood coming from the cystic veins as well as the inferior mesenteric gastric veins. The hepatic vein is one of the most important portal venous systems in the human body and it is integral to the circulatory system in general.

There are many medical conditions and ailments that can affect the hepatic portal system. It is important to diagnose these ailments as early as possible because leaving these problems untreated can cause serious medical conditions and, even worse, death. Portal hypertension is an example of a condition that can affect the hepatic portal system. This is often caused by cirrhosis and can lead to more serious problems if left unchecked.

Since the portal venous system drains blood from the gastrointestinal tract to the liver, this means that any compounds and substances that are absorbed from the small intestines will pass through the liver before going back to the heart. However, it is important to note that not all of the blood coming from the gastrointestinal tract passes through the hepatic portal system. Some of the blood from the gastrointestinal tract travels through other avenues of the circulatory system. Aside from that, blood coming from the pancreas and the spleen also pass through the hepatic portal system.

The hepatic portal system drains blood from the gastrointestinal tract to the liver for a very good reason. This is because many of the drugs and medications that humans take need to be metabolized by your liver before it is passed on to the rest of your body. This process is often referred to as the first pass effect. This is an important function of the human circulatory system.
