2. a. Veins convey the blood
Characteristics
of Vein
a. Veins convey the blood
from peripheral organs
to the heart.
b. Tributaries, venules
drain to big veins.
(It is not called a branch
but a tributary,from a
small D to a large D.)
c. No pulse of vein able
to be felt in living body.

3. 2.The systemic veins are divided into two sets: Superficial veins
Deep veins
① Located beneath the skin
② No correspondingly
accompanied arteries
1) Superficial Veins
(subcutaneous vein)

4. 2) Deep Veins (venae comitantes) ①accompanied with the
corresponding arteries
②having the same names
as those described in the
corresponding arteries

5. 3. There are valves in veins of extremities The valves open toward
the heart
to prevent the
backflow of
blood into
the peripheral
organs.

6. Composition of Systemic Veins 1. Superior vena cava
and its tributaries
2. Inferior vena cava
3. Veins of the heart

7. Composition and Tributaries
of Superior Vena Caval System
Subclavian
Vein
Internal
jugular V
Venous angle
Left / right
brachiocephalic Vs
Superior
vena cava
Right atrium

8. Collectiing Scope of Superior Vena Cava
It receives the blood
from head , neck,
upper limbs & thorax.

9. ⑤Internal jugular V Veins of Head & Neck ①Superior temporal V
②Facial V
③Maxillary V
④External jugular V
⑤Internal jugular V

10. Veins of Neck (anterior view)

11. The facial V communicates
with the cavernous sinus
Sup. Ophthalmic V
Cavernous
sinus
Facial V

12. Veins of Upper Limbs 1.Superficial V 1) cephalic(lat.)
2) basilic(med.)
3 )median viens
Clinical Applications
A) intravenous injection
B) blood sampling
C) blood/ liquid
transfusion
D) introduction of
catheters to the heart or
the coronary arteries

15. Veins in Abdominal Cavity
----Inferior Vena
Caval System
1. Composition
Left / Right
common iliac vein
2.Tributaries
1) parietal
2) visceral
3) paired,
4) unpaired
3. Drainage
lower half of body
4. End
right atrium

16. Tributaries of Inferior Vena Cava 1) Parietal tributaries
2) Visceral tributaries
① Renal V
②Testicular V
(ovarian V)
③Hepatic V--3 tributaries
(submerged in the liver)

18. Veins in Pelvis Internal iliac vein The venous plexuses
in the pelvis are:
1)Vesical venous plexus
2)Uterine venous plexus
3)Rectal venous plexus
All the plexuses
lack valves to enable
the blood to freely flow
forward or backward
(bi-directional flows).

19. Veins of Lower Limb 1) Superficial Veions ① Great saphenous V
tributaries:
a) Superficial epigastric V
b) Superficial iliac circumflex V
c) External pudendal V
d) Superficial medial femoral V
e) Superficial lateral femoral V
② Small saphenous V
(origin,route,ending)

20. 2) Deep Veins Common iliac V External iliac V Femoral V Popliteal V
Anterior tibial V
Posterior tibial V
Common iliac V

21. Splenic V Superior mesenteric V ④ Hepatic Portal Vein
1. Composition:
splenic V, superior mesenteric V
(both union behind the head of pancreas)
Superior mesenteric V
Splenic V

22. 2.Origin: capillaries of unpaired organs of abdomen
3.End: hepatic sinuses
liver sinus
Hepatic portal V

23. Hepatic V
Hepatic portal V

24. 3. Collection Coverage Unpaired organs in abdominal cavity include:
gallbladder,
pancreas,
spleen and
digestive canal from
stomach downward,
except for the liver.

25. 4.Tributaries of
Hepatic Portal Vein
(1) Splenic V
(2) Superior
mesenteric V
(3) Inferior
(4) Left gastric V
(5) Right gastric V

26. 2) Rectal venous plexus 1) Esophageal venous plexus
5. Anastomoses
a. position: low part
b. sigificance : broken,vomiting blood.
a. position: rectum
b. sigificance : blocked,hemorrhoids.
1) Esophageal venous plexus
2) Rectal venous plexus
3)Periumbilical
venous plexus
a. position:
around umbilicus
b. siginificance:
blocked,
visibly swellen.

30. bile reabsorbed (Nutrients) Food
6. Characteristics of Hepatic Portal V
Transporting
thesubstances
absorbed by
stomach &
intestines,
include
nutrients,
toxins,
drugs
& wastes,
etc.
bile reabsorbed

Food

31. (2) Diversion of Blood Stream ▲The blood from superior mesenteric V
flows into the right lobe.
▲ The blood from
splenic V flows
into the left lobe.

32. (3) The both ends of hepaticportal vein are capillaries.

33. The substances absorbed by the small intestine
are carried out of body with blood and urine
though the following pathway:
Small intestine→sup.mesenteric V →
hepatic portal V → Liver sinusoids →hepatic V →
inf.vena cava → R.atrium → R.ventricle →
pulmonary trunk,and L. R pulmonary arteries →
lungs→ pulmonary Vs → L. atrium →
L.ventricle → aorta → renal As → kidneys→
ureters→Urinary bladder → urethra

34. Glucose is injected into median cubital V ,
Trace the sugar until it run out of the body:
Cephalic V →Subclavian V → Branchiocephalic V
→ Sup. Vena cava → R.atrium……(continue…
please think about the subsequent course !!! )

35. Clinical Consideration What may happen after the hepatic
portal vein is obstructed ?
a) building collateral circulations
b) disfunctions of digestive tract
c) toxin to brain
d) poor nutrition supply
