Which Group is Incorrect

Question

Which group is incorrect?
A) Cations: sodium, potassium, calcium
B) Acid-base imbalances: acidosis, alkalosis
C) Lines of defense against acid-base imbalance: buffers, lungs, kidneys
D) Transcellular fluids: aqueous humor, cerebrospinal fluid, plasma

Accepted Answer

The group of transcellular fluids is incorrect because plasma is not a transcellular fluid. It is an extracellular fluid found outside of cells. The other two fluids, aqueous humor and cerebrospinal fluid, are examples of transcellular fluids because they are found in specific spaces within the body and are separate from the rest of the extracellular fluid.
