It comprises the fluid-filled areas between cells and the structural components that support them. This space is not simply empty but is filled with a complex mixture of water, ions, small molecules, and large macromolecules like proteins.
The extracellular space plays a critical role in cell-to-cell communication and the transport of nutrients and
Major components of the extracellular space include the interstitial fluid, which bathes most cells; blood plasma,
