Most fluid in the body is in the extracellular fluid (ECF) compartment.
A
False
B
True
Verified step by step guidance1
Understand the two main fluid compartments in the body: intracellular fluid (ICF) and extracellular fluid (ECF). The ICF is the fluid within cells, while the ECF is the fluid outside cells, including interstitial fluid and plasma.
Recognize that the majority of the body's fluid is actually contained within the cells, making the intracellular fluid (ICF) the largest compartment.
Compare the volumes of the ICF and ECF. The ICF typically accounts for about two-thirds of the total body water, while the ECF accounts for the remaining one-third.
Consider the components of the ECF, which include interstitial fluid (the fluid between cells) and plasma (the fluid component of blood). These components together make up the ECF, but still represent a smaller volume compared to the ICF.
Conclude that the statement 'Most fluid in the body is in the extracellular fluid (ECF) compartment' is false, as most fluid is actually in the intracellular fluid (ICF) compartment.
