General introduction of the veins Vessel which return the blood back to atrium No pulsation,veneous blood, metabolic material, dark red color With thin wall, less elasticity & large irregular cavity With venous valve especially in lower limb, anastomose to form venous network or plexus Superficial (subcutaneous) vein common used to clinic puncture & deep (accompanied) vein Artery - branch; vein-tributary
General introduction of the vein With rich anastomosis, varience is common Special vein:sinuses of dura mater; diploic veins Cardiac vein system, systemic and pulmonary circulatory vein system Drainage factors: venous valve, aspiration of the heart, negative pressure, pressurization of neighbouring muscle contracting
General introduction of the vein In the thoracic cavity, arterial pulsation, gravity & the change of body position Venous plexus is easy to bleeding, compressing can stop bleeding two vein accompanied one artery in forearm & leg Superficial vein could be used for venous puncture Name: from acompanying artery-renal vein, location-facial, portal v,

System of inferior vena cava Organization: Formed by left & right common iliac veins at the level of the lower border of the fifth lumbar vertebrae. Routine: Ascend along the right side of The abdominal part of the aorta And enter the right atrium finally. Collecting venous blood scope: To receive the blood from the abdominal wall, abdominal organs and the lower limb

After woman is pregnant, why does she develop the swelling in right lower limb sometimes? Especially pay attention to the relation between right common iliac artery and vein.
Hepatic portal vein Portal v Formed by sup. mesenteric vein and splenic vein Received venous blood from unpaired organ of abdominal cavity Splenic v Inf,mesenteric v Sup,mesenteric v
Features of hepatic portal vein Two ends are network of capillary Without functional venous valve
Features of hepatic portal vein To form anastomosis between superior vena cava and inferior vena cava. through esophageal venous plenux, rectal venous plexus and paraumblical venous plexus.
