Question

15 questions about the anatomy of the cardiovascular system :
question 5 :
the _______ is indicated by number 11 :
inferior vena cava
descending aorta
subclavian artery

Explanation:

To solve this, we analyze the cardiovascular system anatomy:

• The inferior vena cava (IVC) carries deoxygenated blood from lower body to heart, but number 11 is in the arm/chest region, not lower body. Eliminate this.
• The descending aorta carries oxygenated blood down the torso, but number 11 is in the arm's vascular pathway. Eliminate this.
• The subclavian artery supplies blood to the arm, neck, and chest. Number 11's position (in the arm's vascular network) matches the subclavian artery's distribution (extending into the arm).

Answer:

subclavian artery
