Final answer:
Anaphoresis is the process that infuses an alkaline product into tissues from the negative pole toward the positive pole, associated with iontophoresis and electrotherapy treatments.
Step-by-step explanation:
The process that infuses an alkaline product into the tissues from the negative pole toward the positive pole is known as anaphoresis. This is achieved during the application of an electrical current in a process called iontophoresis, of which anaphoresis is a specific type. The current drives the negatively charged ions (from the alkaline product) towards the positive pole, which is the typical direction of migration for anions in electrotherapy treatments.
