What fluid lies between the cells in tissues?

• A. Interstitial fluid
• B. Plasma
• C. Lymph
• D. Cerebrospinal fluid

Answer: (A)

The fluid between cells in tissues is interstitial fluid. It makes up part of the extracellular fluid and sits in the spaces surrounding cells, providing the medium through which nutrients, gases, and wastes diffuse to and from cells. It is formed from plasma that has filtered across capillary walls and then bathes the cells before some of it returns to blood or becomes lymph. Plasma remains inside blood vessels, lymph is the fluid that moves through the lymphatic system after interstitial fluid enters lymphatic capillaries, and cerebrospinal fluid is found in the brain and spinal cord spaces, not in the tissue interstitium.
