Insects do not have veins in the same way that vertebrates do. Instead, they possess a system of tubes called tracheae that deliver oxygen directly to their tissues. Their circulatory system is open, meaning that hemolymph (the insect equivalent of blood) flows freely within the body cavity rather than being confined to vessels. Thus, while insects have a circulatory fluid, it does not involve veins as found in mammals.

What are the three veins that form and empty the hepatic portal vein?
The hepatic portal vein is created by the anastamoses between the superior mesenteric vein and spleinc vein. It is arguable that the inferior mesenteric vein joins at this same anastomoses but generally it actually joins the splenic vein which then meats the sup. mesenteric vein as stated above. The veins that drain into the portal vein (ie above the ansastmoses between the splenic and sup. mesenteric) are the cystic vein, the right gastric vein and the posterior-superior part of the pancreaticoduodenal vein.
