For my class, I had to measure blood pressure by feeling the radial and ulnar artery. My work sheet asks me what happened when I depressed radial artery and the ulnar artery? And what it suggests about blood flow to fingers? My response to radial artery is "depression causes blood flow to become turbulent and obstructs blood flow." Is this also the same answer for ulnar artery? And how is this related to blood flow to fingers?
