👉 The second fluid, often referred to as the aqueous phase or aqueous solution, is a liquid that exists in a biological context and plays a crucial role in various physiological processes. Unlike the first fluid, which is typically water, this second fluid can include a variety of solutes such as salts, sugars, amino acids, and other organic molecules. It is integral in maintaining cellular homeostasis, facilitating nutrient transport, and supporting biochemical reactions within cells. This fluid is particularly important in the cytoplasm of cells, where it interacts closely with cellular components to ensure proper function and survival.
