Front 16

great saphenous vein:

Back 16

-superficial vein of lower extremity
-superior to medial malleolus and medial side of leg and thigh
-empties inot femoral vein
-often used for coronary artery bi-pass graft

Front 17

small saphenous vein:

Back 17

-superficial vein of lower extremity
-behind lateral malleolus up the back of leg
-empties into portal vein

Front 18

veins of thorax:

Back 18

-superior vena cava, inferior vena cava, internal thoraxix veins
-azygose system found in this region

Front 19

superior vena cava:

Back 19

-vein of thorax
-drains arm and head
-azygos system drains into superior vena cava (by arch of azygos)

Front 20

inferior vena cava:

Back 20

-vein of thorax
-drains abdomen and lower extremity

Front 21

internal thoraxcic veins:

Back 21

-vein of thorax
-drains intercostal veins ventrally

Front 22

azygos system:

Back 22

-system of veins
-drain intercostal veins dorsally
-empties into superior vena cava by the arch of azygos
-contain three veins: azygos, hemiazygos, accesory hemizaygos veins
-pattern of veins is different for everyone

Front 23

azygos vein:

Back 23

-vein of azygos system
-ascends along right/center of thoracic vertebral bodies
-receives all posterior intercostal veins
-drains into superior vena cava

Front 24

hemiazygos vein:

Back 24

-vein of azygos system
-drains into superior vena cava
-ascends left side of vertebral column
-receives 9th-11th posterior intercostal veins and subcostal veins

Front 25

accessory hemiazygos:

Back 25

-vein of azygos system
-recieves 4th08th left posterior intercostals
-drains into arch of azygos

Front 26

veins of the abdomen:

-internal and external iliac veins, common iliac veins, interior vena cava, femoral vein, renal vein, gonadal veins

Front 27

internal and external iliac veins:

Back 27

-vein of abdomen
-both together form common iliac veins
-in pelvis

Front 28

femoral vein:

Back 28

-vein of abdomen
-in thigh
-becomes external iliac vein in pelvis

Front 29

renal veins:

Back 29

-vein of abdomen
-carry blood from kidney
-empties into IVC
-left renal vein: longer than right
--because: it crosses over the top of aorta

Front 30

gonadal veins:

Back 30

-veins of abdomen
