Vein retroperitoneal and runs to the right and roughly parallel to the abdominal aorta along the spine. Large veins feed into these two veins, and smaller veins into these. Together this forms the venous system. Whilst the main veins hold a relatively constant position, the position of veins person to person can display quite a lot of variation. The pulmonary veins carry relatively oxygenated blood from the lungs to the heart. The superior and inferior venae cavae carry relatively deoxygenated blood from the upper and lower systemic circulations, respectively. The portal venous system is a series of veins or venules that
Jugular vein resolution, or coup-de-grace. An alternate explanation for the phrase suggests "to go for the jugular" merely means to attack without restraint. The jugular vein system is essential but not particularly weak or vulnerable, because this venous system is generally found fairly deep in the body. Jugular vein The jugular veins are veins that take deoxygenated blood from the head back to the heart via the superior vena cava. There are two sets of jugular veins: external and internal. The left and right external jugular veins drain into the subclavian veins. The internal jugular veins join with the subclavian veins more
