The bones (purple) are also seen on the X-ray, aiding identification of the arteries. The head (upper right) has been turned to one side to expose the right-hand side of the neck and its carotid arteries (internal and external). These arteries bring oxygenated blood to the head. The right arm (centre left) has been raised to show how the subclavian artery passes under the collar bone (clavicle) and into the arm. The arteries carry oxygenated blood from the heart (not seen). The arteries have been highlighted arteriographically by injecting them with a radio-opaque dye, creating a medium to absorb the X-rays. ๐ทโขMedicogramโข #letslearn #angiogram #xray #arteriogram #surgery #trending #now #medicine #medicogram
