👉 A loud fluid, often referred to as a hypertonic or isotonic solution, is a substance that has a higher concentration of solutes compared to the surrounding biological fluid, such as blood plasma. When this fluid comes into contact with a less concentrated solution inside the body, water moves out of the cells and into the fluid to balance the solute concentration, creating a noticeable bubbling or foaming effect. This phenomenon is commonly observed in conditions like osmosis, where the fluid moves to equalize solute concentrations, or in certain medical settings like dialysis, where hypertonic solutions are used to draw fluid out of tissues.
