Question

15 questions about the anatomy of the cardiovascular system :
question 1 :
the _______ is indicated by number 15 :
radial artery
brachial artery
ulnar artery

Explanation:

To determine the structure indicated by number 15 in the cardiovascular system diagram (focusing on the arm's arterial anatomy), we analyze the options:

• The radial artery is typically located along the radial (thumb - side) aspect of the forearm. In the diagram, number 15's position in the forearm (thumb - side region) aligns with the radial artery's anatomical location.
• The brachial artery is in the upper arm (brachium), not the forearm where number 15 is.
• The ulnar artery is along the ulnar (pinky - side) aspect of the forearm, which is a different location than where number 15 is shown.

Answer:

radial artery
