Questions: Approximately of total body water is contained in the extracellular fluid compartment. The remaining of total body water is contained in the intracellular fluid compartment. The extracellular fluid compartment is subdivided into the plasma and interstitial compartments in a to ratio.

The answer is:

Approximately one-third of total body water is contained in the extracellular fluid compartment. The remaining two-thirds of total body water is contained in the intracellular fluid compartment. The extracellular fluid compartment is subdivided into the plasma and interstitial compartments in a 1:3 ratio.

Explanation:

1. Total body water is divided into two main compartments: intracellular fluid (ICF) and extracellular fluid (ECF).
2. Approximately two-thirds of total body water is found in the intracellular fluid compartment, while the remaining one-third is in the extracellular fluid compartment.
3. The extracellular fluid is further divided into plasma and interstitial fluid. The typical ratio of plasma to interstitial fluid is approximately 1:3. This means that for every part of plasma, there are about three parts of interstitial fluid.
