Dorsal:

V. cava inferior → V. lumbalis ascendens → (Zwerchfell) V. azygos (rechts) bzw. V. hemiazygos (links) → V. cava superior

Ventral:
- V. cava inferior → V. iliaca communis → V. iliaca externa → V. epigastrica inferior → V. epigastrica superior → V. thoracica interna → V. subclavia → V. brachiocephalica → V. cava superior

Question 2

Portocavale Anastomose

(Leberzerose)

Ösophagus:
V. portae hepatis → Vv. gastricae → Vv. oesophageales → V. azygos (rechts) bzw. V. hemiazygos (links) → V. cava superior

=> Ösophagusvarizen

Parazmbilical:
Kreislauf: V. portae hepatis → Vv. paraumbilicales → V. epigastrica inferior → V. iliaca externa → V. iliaca communis → V. cava inferior

=> Caput Medusae (Varizen, Erweiterung der Venengefäße

• Rektumvenen: V. Mesenterica inferior -> V. Rectalis superior (Pfortadersystem) aber media und inferior -> Vv Iliacae communes -> Azygos -> Cava superior
  => Hämoriden
• Kolonvenen
