Through Which Blood Vessel Does Blood Flow on Its Way

Question

Through which blood vessel does blood flow on its way from the axillary vein to the right atrium?
A) Coronary sinus
B) Subclavian vein
C) Inferior vena cava
D) Jugular vein

Accepted Answer

The subclavian vein is the direct continuation of the axillary vein as it moves medially towards the chest. Blood flows from the axillary vein into the subclavian vein and then continues its journey towards the heart, eventually draining into the superior vena cava, which then empties into the right atrium. The other options do not directly connect the axillary vein to the right atrium in the pathway described.
