👉 The migration fluid refers to the substance that enables the movement of ions and molecules within cells, playing a crucial role in various biological processes. This fluid, primarily composed of water and electrolytes, facilitates the transport of nutrients, waste products, and signaling molecules across cell membranes. It is essential for maintaining cellular homeostasis, enabling processes like nerve impulse transmission, muscle contraction, and pH regulation. The fluid's dynamic nature allows it to adapt to cellular needs, ensuring efficient transport and communication within and between cells.
