Final answer:
The process of forcing solutions through the skin using the galvanic current is called iontophoresis, which is utilized in medical treatments and diagnoses due to the body's lower resistance to electric current once the skin barrier is bypassed.
Step-by-step explanation:
Forcing solutions through the skin using the galvanic current is referred to as iontophoresis. This process occurs by applying a weak electric current to the skin, which facilitates the delivery of medication or other chemicals into the body. The technique makes use of the basic principles of electrolysis, where an external power source is used to drive a nonspontaneous redox reaction. In the context of the human body, most of the resistance to electric current is due to the dry skin. However, when the skin's resistance is bypassed using techniques such as iontophoresis, the interior fluids and ionic solutions of the body allow the passage of current more readily, and this can have therapeutic effects or be used in medical diagnoses.
