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?

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?

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?
