The advent of high-technology ultrasound and pulsed Doppler has overcome some of the limitations of early studies. Veins are blood vessels that carry blood towards the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.

This is assisted by a series of one-way valves. The regulation of blood flow through the blood vessels and to the tissues is under ex fairly compl control of the brain and nervous system as well as local chemicals which may be released by the tissues. The main place of resistance to the venous flow out of the splanchnic vasculature is located within the hepatic veins15,35–37or within the liver itself.37One way or the other, an increase in resistance within the distal part of the splanchnic venous system would impede the outflow of blood from splanchnic organs, sequestering blood within the liver and more proximal parts of the splanchnic Venous thromboembolism (VTE) occurs when blood clots develop in the veins that carry blood to your heart. It includes deep vein thrombosis and pulmonary thrombosis.

Venous insufficiency is defined as retrograde blood flow in the venous system resulting from incompetence of the venous valves. It is the most common pathologic process affecting the venous system.
