Question

Where do the superior nasal wall veins drain into?

A) Inferior vena cava
B) Brachiocephalic vein
C) Jugular vein
D) Hepatic portal vein

Answer 1

The superior nasal wall veins drain into the inferior vena cava through the brachiocephalic veins.

Step-by-step explanation:

The superior nasal wall veins drain into the inferior vena cava. The superior vena cava is a large systemic vein that drains blood from most areas superior to the diaphragm and empties into the right atrium of the heart. It receives blood from the head and neck through the brachiocephalic veins, which are formed by the fusion of the external and internal jugular veins, among other vessels.
