Where does the Internal Jugular Vein start? What does it end up as?
Starts
- Level of the Jugular Foramen
ends
- Joins subclavian to form the brachiocephalic vein

- Cephalic Vein (lateral)
- Basilic (medial)
Where do the Superficial Veins of the Upper limb arise from?
- The Dorsal Venous Plexus on the dorsum of the hand
How are the Cephalic Vein and the Basilic Vein Connected?
- By the median cubital vein at the level of the cubital fossa
Where do the Cephalic Vein and Basilic Vein Drain?
- The Axillary Vein
Where do the Deep Veins of the Upper Limb drain into?
- The Axillary Vein
What does the Axillary Vein continue as?
- the Subclavian Vein after the lateral border of rib I
What are the 6 names of the Deep Veins of the Upper Limbs?
- Dorsal Palmar Veins
- Radial Vein
- Ulnar Vein
- Brachial Vein
- Axillary Vein
- Brachiocephalic
What are the Deep Veins of the Lower Limb?

- Posterior Tibial Vein (medial posterior)
- Fibular Vein (lateral posterior)
Where do the Deep Veins empty into? What is the exception?
Empty
- The Femoral Vein
Exception
- the Gluteal Region Veins (into the internal iliac vein)
What are the Superficial Veins of the Lower Limb?
- Small Saphenous Vein (lateral side)
- Great Saphenous Vein (medial side)
Is the Small saphenous vein superficial or deep? What does it drain into?
- Superficial
- Drains into the popliteal vein
Is the great saphenous vein superficial or deep? Where does it drain into?
- Superficial
- Drains into the Femoral Vein
Where does the Femoral Vein drain into?
- The External iliac Veins
Where does the venous blood that trains into the superior vena cava come from?
- The head and neck
- The upper limbs
- The thorax
What Veins drain the venous blood from the head and neck?
- Internal Jugular
- External Jugular (minor)
What Veins join to form the Brachiocephalic?
- The Subclavian
- The Internal Jugular
The does the venous blood from the thoracic wall drain?
- The Anterior and Posterior Intercostal Veins
Where do the Anterior Intercostal Veins get collected? where does it go after?
- Internal Thoracic Vein: goes into the Brachiocephalic Vein
Where does the right side of the Posterior Intercostal Veins drain?
- The Azygos Vein
What are the two parts of the left side of the posterior intercostal veins? Where do they drain?
- Lower Part: Into the Hemiazygos Vein
- Upper Part: Into the Accessory Hemiazygos Vein
What do the Hemiazygos and Accessory Hemiazygos Veins have in common?
- They both cross the midline
- They both Drain into the Azygos Vein, Which in turn, drains into the SVC
What is the Inferior Vena Cava formed by?
- Left and Right Common Iliac Veins at the LV vertebrae
Where does the Inferior Vena Cava receive Venous Blood from?
- Lower Limbs
- Pelvis
- Abdomen (except the abdominal part of the GI tract, spleen, and pancreas)
What drains directly into the Inferior Vena Cava?
- Right Gonadal
- Left and Right Renal Veins
Where does the Left Gonadal Vein drain?
- The Left Renal Vein
Is the Hepatic Portal Vein the same as the Hepatic Vein?
- No
Where does the Hepatic Portal System receive venous blood from? Where does it drain?
- The GI tract: drains directly into the Inferior Vena Cava
How does Venous blood from the liver get back to the heart?
- Drains into the Inferior Vena Cava via the Hepatic Veins
- Inferior Vena Cava then goes to the Right Atrium
How is the Hepatic Portal Vein Formed?
- The Superior Mesenteric Vein joins the Splenic Vein
What drains into the Superior Mesenteric Vein? (6)
- Colon
- Intestines (except the upper part of the duodenum)
- Cecum
- Appendix
- Ascending Colon
- Transverse Colon
Where does the Splenic Vein Recieve venous blood from?
- spleen
- parts of the stomach
- parts of the pancreas
- inferior mesenteric vein
Where does the Inferior Mesenteric Vein get venous blood from?
- left splenic flexure of the colon
- descending colon
- sigmoid colon
- the rectum
Where do the foregut organs drain venous blood?
- Directly into the hepatic portal vein
