lec6 part 2 Flashcards
deep veins of the upper limb are situated
underneath the deep fascia
deep veins of the upper limb are
paired veins
Superficial & deep palmar venous arches Lie in the
subcutaneous tissue proximal to Metacarpophalangeal joints
veins empty into two radial & two ulnar veins
Superficial & deep palmar venous arches
paired veins
radial &
ulnar veins
Brachial veins
veins drain the hand
two radial & two ulnar veins
two radial & two ulnar veins unite to form
Brachial veins
Brachial veins are situated
either side of the brachial artery
vena comitantes.
Veins are structured in way that The pulsations of the artery assists the
venous return
Perforating veins run between
the deep and superficial veins of the upper limb, connecting the two systems
to keep the blood moving toward the heart, that if one vein is closed the blood in it will move toward the other vein.
Radial vein is
deep vein
Radial vein draining
the radial side of the forearm
Radial vein unites with
the ulnar vein just distal to the elbow joint to form the brachial vein
brachial vein formed from
Radial vein unites with the ulnar vein just distal to the elbow joint
Ulnar vein is
deep vein
Ulnar vein draining
the ulnar side of the forearm
Brachial vein begins at
elbow via a union of the radial & ulnar veins travels up the arm to form the axillary vein
Axillary Vein Formed by
the union of the Brachial veins (vena comitantes of brachial artery) with basilic vein
Axillary vein lies
on the medial side of the axillary artery and runs deep to the pectoralis minor muscle
Axillary Vein Begins
the inferior border of the teres major
muscle
Subclavian vein
large vein
Subclavian vein is
continuation of the axillary vein
Subclavian vein begins
on the lateral border of the 1st rib
Subclavian vein ends at
the medial border of the anterior scalene muscle
Subclavian vein unites with
the internal jugular vein
brachiocephalic vein is formed by
union of Subclavian vein with the internal jugular vein
Left brachiocephalic vein pass
behind the manubrium sterni.
The brachiocephalic veins unite to form
the superior vena cava
major vessels enter Right Atrium:
Superior vena cava,
inferior vena cava and
Coronary sinus
superior vena cava drains
Azygos system (Right and left) Brachiocephalic veins
inferior vena cava drains
a. Paired hepatic veins
b. paired phrenic veins
c. Right suprarenal vein
d. paired renal veins
e. right gonadal veins
f. paired common iliac veins
Tributaries of IVC
asymmetrical
• Left gonadal and left suprarenal veins drain into the left renal vein
• On the right side. the right
gonadal and right suprarenal veins drain directly into IVC
• Right and left hepatic veins enter superior part of IVC
testicular vein
The gonadal vein in males
ovarian vein
Gonadal vein in females
Veins of the lower limb
Common iliac vein drains femoral vein drains popliteal vein peroneal vein anterior tibial vein posterior tibial vein small saphenous vein great saphenous vein
Common iliac vein drains
1) Internal iliac vein, drains the pelvic organs
(2) External iliac vein receives blood from the femoral vein
femoral vein drains
- popliteal vein
2. great saphenous vein
popliteal vein drain
a. peroneal vein (fibular vein)
b. anterior tibial vein
c. posterior tibial vein
d. small saphenous vein
Femoral becomes
after
external iliac ,crossing under inguinal
ligament.
External iliac joins with
internal iliac to form common iliac vein
Both popliteal vein and artery passes through a canal called
Adductor foramen (canal or hiatus)
Adductor foramen (canal or hiatus) found
in adductor magnus muscle
the popliteal vein becomes
after
femoral
passing from Adductor foramen (canal or hiatus)
Portal System has TWO capillary beds
Digested material is absorbed from the digestive system by one capillary bed
→ Goes to the liver for processing through a second capillary bed →Blood returns back from the liver to the venouscirculation (inferior vena cava) via the hepatic veins (2 –4)
Portal vein is formed from the
- Superior mesenteric vein
- Splenic vein
- Inferior mesenteric vein
Portal system Picks up
digested nutrients from stomach & intestines through the superior mesenteric,
splenic and inferior mesenteric veins . Portal vein divides into capillaries and delivers the blood to liver for processing and storage
