What Mechanisms Are Involved in Volume Regulation?
Two primary mechanisms are involved in cell volume regulation: the Regulatory Volume Increase (RVI) and the Regulatory Volume Decrease (RVD). RVI is activated when cells shrink due to osmotic stress, leading to the uptake of ions and water to restore normal volume. Conversely, RVD is triggered when cells swell, resulting in the release of ions and water to return to their original size.
