Plasma and interstitial fluid account for most of the volume of ________ in the body.

Question

Quizplus · Accepted Answer

Plasma and interstitial fluid are both examples of extracellular fluid, which makes up the majority of the fluid found outside of cells in the body. Serum is the fluid left over after blood has clotted and does not contain clotting factors, so it is not a major contributor to overall fluid volume. Lymphatic fluid is a specialized fluid found within the lymphatic vessels, which is not as abundant as extracellular fluid. Whole blood includes both the cellular components (red and white blood cells) and the plasma, so it is not solely composed of extracellular fluid. Packed blood refers to a specific type of blood product that has had most of its plasma removed, so it would not be a major contributor to overall fluid volume.
