2. Cerebrospinal fluid: This fluid surrounds the brain and spinal cord. It is also considered an extracellular fluid as it is located outside the cells.
3. Blood plasma: This is the liquid component of blood, in which blood cells are suspended. It is an extracellular fluid because it is outside the cells.
4. Cytosol: This is the fluid found inside cells, making it an intracellular fluid, not an extracellular fluid.
