Question

Which of the following ﬂuid compartments is not a partner in immune function?
A) Intracellular ﬂuid
B) Blood stream
C) Extracellular ﬂuid
D) Lymphatic system

Accepted Answer

The intracellular fluid is not directly involved in immune function. The immune system operates primarily in the bloodstream, extracellular fluid, and lymphatic system, where immune cells and substances can move to detect and respond to pathogens. Intracellular fluid, on the other hand, is the liquid found inside cells and does not directly participate in these immune processes.
