The unguided white fragments entered the aorta and circulated in her body. If they weren't stuck, they would probably arrive later, actuated by the formless force pulling the white fragments from the spinal cord.
She was unable to generate much force through her Will. Being a Warrior, the strength of her Will was inferior to an Esper. But still, Warriors were taught methods of their own to tide through the issue. The first was to make use of the insane pumping force present in the heart.
When the blood was pumped in the left ventricle, her Will redirected the white fragments, using the momentum of the pressurised flow to collide into the Heart Crystal. After that, she rearranged the layer of white fragments over the Heart Crystal in such a way that they would be better compressed under the blood pressure.
