Overview
Features
form
Compared with accompanying arteries, veins have thin and soft walls, larger diameters, less elasticity, lower pressure, and slower blood flow.
structure and layout
The free edge of the venous valve faces toward the heart. Venous valves ensure the centripetal flow of blood and prevent blood from flowing backward. The veins in the limbs that are more affected by gravity have more valves, while the larger veins in the trunk have fewer or no valves.
Systemic veins are divided into superficial and deep veins
deep vein
Accompany arteries and nerves
The anastomotic branches of veins are relatively abundant

Features
Multiple anastomoses with the superior and inferior vena cava
Does not contain static valve
Function
hepatic portal hypertension
Phenomenon
Vomiting blood, blood in stool, abdominal varicose veins
principle
When the hepatic portal vein reflux is blocked, because there are no venous valves in the hepatic portal vein and its branches, blood can flow back to the superior and inferior vena cava through the anastomotic branches. In this case, the anastomotic branches expand, causing the abdominal wall veins, esophageal venous plexus, and rectal venous plexus. If the dilated veins of varicose veins rupture, vomiting blood or blood in the stool may occur.
