1. vertebral vein (posterior neck)
2. external jugular vein (face & scalp)
3. internal jugular vein (brain)
Where does most blood drain through in the cranial cavity?
dural venous sinuses
What are dural venous sinuses?
large modified veins between two layers of dura mater
What are the parts of the cranial cavity?
1. superior sagittal sinus
2. inferior sagittal sinus...drains into
3. straight sagittal sinus ...drains into (with superior) into...
4. transverse sinus ... drains into (along with cavernous sinus)
5. sigmoid sinus
What are the 3 parts of the azygos system?
1. azygos vein
2. hemiazygos vein
3. accessory hemiazygos vein
How does the azygos vein drain?
drains right side veins & hemi into superior vena cava
How does hemiazygos vein drain?
drain left-side veins
How does accessory hemiazygos vein drain?
drain left-side veins
What are the veins from abdominal cavity?
1. renal veins (kidneys)
2. gondal veins (gonads/repro organs)
3. suprarenal veins (adrenal glands)
4. splenic vein (spleen)
5. gastric veins (stomach)
6. superior mesenteric vein (SI and some LI)
7. inferior mesenteric (rest of LI)
How does the splenic, gastric, sup/inf mesenteric drain?
into hepatic portal vein
After it drains into the hepatic portal vein, where does it go?
It passes through the liver to be detoxified then goes through hepatic veins and drains back into inferior vena cava.
What 2 veins merge to form the brachial vein?
radial vein and ulna vein
The radial vein and ulna veins merge to form the??? How?
brachial vein by antecubital fossa
3 veins drain superficial upper limb

2. median antebrachial vein (medial)
3. basilic vein (medial)
What does the median cubital vein do?
joins cephalic and basilic veins
Where should you draw blood?
at the median cubital vein
By axilla, basilic vein joins brachial vein to form...
axillary vein (until it reaches clavicle)
After the axillary vein reaches clavicle, then it goes to...
subclavian vein
The subclavian vein drains into...
brachiocephalic vein and then into superior vena cava
What are the lower limbs and pelvis veins from inferior vena cava?
common iliac vein --> internal iliac vein & external iliac vein
What does the internal iliac vein drain?
drains pelvis
What does the external iliac vein become?
femoral vein
