VEIN SHANDONG UNIVERSITY Liu Zhiyu Characteristic of veins 1、Capilaris 2.Have a thinner wall and a larger diameter than their corresponding arteries 3. Have venous valves which prevent reflux of blood 4.Form venous plexus and venous rete。 5、。 superficial vein deep vein 6.sinuses of dura mater, diploic veins。 一、 pulmonary veins : right superior pulmonary veins right inferior pulmonary veins Left superior pulmonary veins Left inferior pulmonary veins left atrium 二、 The systemic veins : The composition of systemic veins 1. Cardiac vein system Superior vena cava system Inferior vena cava system (hepatic portal system ) (一)superior vena cava system 1. superior vena cava A. formation: It is formed by the junction of the two brachiocephalic veins B.The scope of collection: It collect the blood from the head ,the neck ,the upper limbs,the thorcic wall and a portion of the organs within thorax 4. The branchiocephalic veins Formation: internal jugular vein subclavicular vein The angle of the union of the internal jugular vein and subclavicular vein is called Venous angle Facial Vein Angular vein Facial Vein Deep Facial Vein 眼上、下 静脉 Pterygoid Venous Plexus 颈内 静脉 海绵窦 2.azygos v. hemiazygos v ⑴azygos v. ⑵ hemiazygos v . ⑶accessory hemiazygos v. (二)The inferior vena cana system 1. inferior vena cana A. formation : The inferior vena cava is formed by the junction of the two common iliac veins B.The scope of collection: The inferior vena cava receives blood from all structure below the diaphragm (3).The common iliac vein • It is composed by the junction of the external and internal iliac veins in front of sacroiliac joint, and collects the blood from the pelvis and the lower limbs 2.Superficial v.of upper limb 上肢浅静脉 (1) cephalic v. : (2) basilic v. : (3)median cubital v. 3. Superficial v.of lower limb (1)great saphenous v. : (2) tributaries: superficial medial femoral v. superficial lateral femoral v. superficial epigastric v. superficial iliac circumflex v. external pudendal v. superficial iliac circumflex v. superficial medial femoral v. external pudendal v. superficial lateral femoral v. superficial lateral femoral v. great saphenous v (四) Hepatic Portal Vein 1、 formation: 2.collection: 3. character 4、 tributaries Superior Mesenteric Vein Splenic Vein Inferior Mesenteric Vein Left Gastric Vein Right Gastric Vein Cystic Vein Paraumbilical Vein
