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

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.
