Blood plasma and lymph

C.

Intracellular fluid (IGE)

D.

Tissue (interstitial) fluid

Answer and Explanation

The Correct Answer is C

A. Extracellular fluid (ECF) includes all the fluid outside of cells, such as interstitial fluid, blood plasma, and lymph. However, the majority of body water is found inside the cells.

B. Blood plasma and lymph are components of the extracellular fluid. Although they contain water, they do not hold the greatest volume compared to intracellular fluid.

C. Intracellular fluid (ICF) refers to the fluid within the cells, and it constitutes the largest volume of water in the body.

D. Tissue (interstitial) fluid is part of the extracellular fluid found between cells. While it contains a significant amount of water, it does not account for the greatest volume in the body.

C. Large intestine has lymphoid nodules, but it does not contain as much lymphoid tissue as the small intestine.
