Chapter 29, Problem 29.27AP

Interpretation Introduction

Interpretation:

The major cations found in interstitial fluid have to be given.

Concept Introduction:

Body fluids: About $\text{60\%}$ of human body is water and this water occupies in two departments called the intracellular and extracellular compartments.

Intracellular fluid: The fluids inside the cells are known as intracellular fluids. The major cations in intracellular fluids are potassium, sodium and magnesium and the major anions is phosphorus.

Extracellular fluid: The fluids outside the cells and it include mainly plasma and interstitial fluid. The major cations in extracellular fluids are potassium, sodium and magnesium, calcium and the major anions are phosphorus and chloride.

Extracellular fluids include interstitial fluids and plasma. The fluid surrounding the cells is known as interstitial fluid and sodium is the major cation found in interstitial fluid.
