Blood is preferentially drawn from veins rather than arteries because arterial puncture carries higher risks of bleeding, hematoma, and complications due to high blood pressure.

The analysis

The claim is a well-established medical fact supported indirectly and directly by literature discussing the higher mechanical risks, bleeding, and management challenges associated with arterial punctures compared to venous access.
