Electrolysis Practice Exam

What happens to the blood supply at the positive pole during electrolysis?

1. Increases blood supply

2. Decreases blood supply

3. Remains the same

4. Obstructs blood vessels

The correct answer is: Decreases blood supply

The correct answer is that the blood supply decreases at the positive pole during electrolysis. This phenomenon occurs because the positive electrode, or anode, has a stimulating effect on the local tissues. It generates positive ions that can lead to a constriction of blood vessels, also known as vasoconstriction. This contraction of blood vessels results in a reduced blood flow to the area surrounding the positive pole. In contrast, at the negative pole, or cathode, an increase in blood supply is often observed due to vasodilation, which facilitates improved blood flow in that region. Thus, the contrast in blood supply dynamics between the positive and negative poles is critical for understanding the physiological effects of electrolysis on tissue.
