What term describes the fluid located outside of the cells?

The term that describes the fluid located outside of the cells is "extracellular." This term encompasses all fluid found outside the individual cells, which includes interstitial fluid (the fluid in the spaces between cells) and intravascular fluid (the fluid within blood vessels). By definition, the extracellular fluid is crucial for transporting nutrients, oxygen, and waste products to and from the cells, thereby facilitating cellular metabolism and overall homeostasis in the body. While interstitial fluid is specifically the fluid between cells and intravascular fluid refers specifically to blood plasma, the umbrella term that includes all of these fluids is extracellular.
