hepatic portal and portal veins
Organs of the circulatory system are the heart, blood, and blood vessels (arteries and veins). The circulatory system interacts with other systems, such as the lungs (respiratory system), liver (digestive system), and kidneys (digestive system).
Yes it does. When food is digested in the large intestine, where the nutrients are absorbed into the blood stream and travel to the liver for further processing. Beyond that, the digestive system is composed of cells which, like any other cells, require oxygen carried by the blood, as well as protection by the immune system, also carried by the blood, and nutrients since the digestive system is not always digesting (except for people who never stop eating - put down that donut!)
From the blood it is pumping, the blood pervades are organs and carries food /energy for those organs to function.
It is absorbed into the blood through the vili in the small intestine.

No. The digestive system is strictly for eating and disposing that food. There is no blood in your stomach (or at least, there is not supposed to be), but there are blood vessels that go around the organs in your digestive system. However, the blood does not go through them.
The single vessel that drains blood from the digestive tract organs to the liver is the hepatic portal vein. Blood flow to the liver is unique, in that it receives both oxygenated and partially deoxygenated blood.
The digestive tract and the liver are connected by the hepatic portal vein. This allows nutrients to pass from the digestive tract to the liver for processing.
hepatic portal vein
No, the stomach and intestines get LESS blood during exercise. The blood is needed in the muscles being used and is shunted there instead of digestive organs
The blood vessels and the heart are lined by the endothelium! The heart is also lined by the epicardium, and is surrounded by the pericardial sac.
The source of blood in the hepatice portal system is the blood in the circulatory system itself. The hepatic portal is not seperate from the rest of the system, it is just a minor detour that takes blood from the digestive organs towards the liver where it can get further processing.
