Practice questions on Total Body Water
Approximately two-thirds of the total body water is found in which fluid compartment?
- Interstitial fluid
- Extracellular fluid
- Plasma
- Intracellular fluid
Answer: D. The intracellular fluid (ICF) compartment accounts for approximately two-thirds (around 28 liters in a 70kg adult) of the total body water. The extracellular fluid (ECF) compartment accounts for the remaining one-third and is further divided into interstitial fluid (A) and plasma (C).
