Answer:
When the cell is engulfing extracellular fluids
Explanation:
Extracellular fluid is the term that exists in an organism but sealed within the body cavities and vessels. It circulates in a circular motion in blood plasma, the liquid component of the blood cells. As the nutrients and oxygen from the blood are transferred out of the blood in the capillaries, these molecules make their ways to another extracellular fluid that is the surrounds of the individual cells within the body. This is also called interstitial fluid and found in cell bodies. The extracellular fluid allows cells to carry out the process using nutrients and oxygen provided and carry wastes back to the blood. It is called the trans cellular fluid. This fluid means to supports the structure, not for exchanges of the molecules.
