  • Small Saphenous Vein (lateral side)

- Great Saphenous Vein (medial side)

21
Q

Is the Small saphenous vein superficial or deep? What does it drain into?

A
  • Superficial

- Drains into the popliteal vein

22
Q

Is the great saphenous vein superficial or deep? Where does it drain into?

A
  • Superficial

- Drains into the Femoral Vein

23
Q

Where does the Femoral Vein drain into?

A
  • The External iliac Veins
24
Q

Where does the venous blood that trains into the superior vena cava come from?

A
  • The head and neck
  • The upper limbs
  • The thorax
25
Q

What Veins drain the venous blood from the head and neck?

A
  • Internal Jugular

- External Jugular (minor)

26
Q

What Veins join to form the Brachiocephalic?

A
  • The Subclavian

- The Internal Jugular

27
Q

The does the venous blood from the thoracic wall drain?

A
  • The Anterior and Posterior Intercostal Veins
28
Q

Where do the Anterior Intercostal Veins get collected? where does it go after?

A
  • Internal Thoracic Vein: goes into the Brachiocephalic Vein
29
Q

Where does the right side of the Posterior Intercostal Veins drain?

A
  • The Azygos Vein
30
Q

What are the two parts of the left side of the posterior intercostal veins? Where do they drain?

A
  • Lower Part: Into the Hemiazygos Vein

- Upper Part: Into the Accessory Hemiazygos Vein

31
Q

What do the Hemiazygos and Accessory Hemiazygos Veins have in common?

A
  • They both cross the midline

- They both Drain into the Azygos Vein, Which in turn, drains into the SVC

32
Q

What is the Inferior Vena Cava formed by?

A
  • Left and Right Common Iliac Veins at the LV vertebrae
33
Q

Where does the Inferior Vena Cava receive Venous Blood from?

A
  • Lower Limbs
  • Pelvis
  • Abdomen (except the abdominal part of the GI tract, spleen, and pancreas)
34
Q

What drains directly into the Inferior Vena Cava?

A
  • Right Gonadal

- Left and Right Renal Veins

35
Q

Where does the Left Gonadal Vein drain?

A
  • The Left Renal Vein
36
Q

Is the Hepatic Portal Vein the same as the Hepatic Vein?

A
  • No
37
Q

Where does the Hepatic Portal System receive venous blood from? Where does it drain?

A
  • The GI tract: drains directly into the Inferior Vena Cava
38
Q

How does Venous blood from the liver get back to the heart?

A
  • Drains into the Inferior Vena Cava via the Hepatic Veins

- Inferior Vena Cava then goes to the Right Atrium

39
Q

How is the Hepatic Portal Vein Formed?

A
  • The Superior Mesenteric Vein joins the Splenic Vein
