Verified step by step guidance

Understand the concept of fluid compartments in the human body. The body is divided into different fluid compartments: intracellular fluid (ICF), extracellular fluid (ECF), which includes interstitial fluid and plasma.

Recognize that intracellular fluid (ICF) is the fluid contained within cells. It makes up the majority of the body's fluid content.

Extracellular fluid (ECF) is the fluid outside of cells and is divided into interstitial fluid (the fluid between cells) and plasma (the fluid component of blood).

Compare the volumes of these compartments: Intracellular fluid accounts for about 2/3 of the total body water, while extracellular fluid accounts for about 1/3, with interstitial fluid being the larger portion of ECF compared to plasma.

Conclude that the intracellular fluid compartment contains the most fluid in the human body, as it comprises the largest portion of total body water.
