Question

Interstitial fluid resembles blood, but with a lower concentration of ________.
A) lipids
B) proteins

Accepted Answer

Interstitial fluid is derived from blood plasma, but with a lower concentration of proteins. The proteins are too large to efficiently pass through capillary walls, so they remain in the bloodstream. The interstitial fluid plays a crucial role in transporting nutrients, gases, and waste products between cells and blood.
