Final answer:
False. Interstitial fluid and intercellular fluid are not identical chemically. Interstitial fluid surrounds cells and has a different composition compared to the fluid inside cells.
Step-by-step explanation:
False. Interstitial fluid and intercellular fluid are not identical when compared chemically. While they both belong to the extracellular fluid, interstitial fluid is the fluid that surrounds and bathes the cells of multicellular animals, whereas intercellular fluid is the fluid that is inside the cells.
The composition of interstitial fluid includes amino acids, sugars, fatty acids, coenzymes, hormones, neurotransmitters, salts, waste products, and some types of white blood cells.
On the other hand, the intercellular fluid contains the same components as intracellular fluid, such as water, electrolytes, and small uncharged molecules that can diffuse across cell membranes, but have a much higher concentration of macromolecules like proteins.
