Question

What is interstitial fluid?

• A. Fluid which removes waste
• B. Fluid which dissolves nutrients
• C. Fluid which occupies spaces between the cells
• D. All of the above

Answer 1

The correct option is C Fluid which occupies spaces between the cells

Therefore, the correct answer is option C.
