Final answer:
The majority of our total body water is located inside cells in the intracellular fluid. This is followed by interstitial fluid which is part of the extracellular fluid and surrounds non-blood cells.answer is option E.
Step-by-step explanation:
The majority of total body water is located inside cells, in a fluid compartment known as the intracellular fluid (ICF). This fluid is contained within cells and is separated from extracellular fluid (ECF) by the plasma membrane. The intracellular fluid is where most of the body's metabolic processes occur as it contains numerous solutes, proteins, and nucleic acids that facilitate cellular function. The second largest volume of fluid in the body is the interstitial fluid, which surrounds all cells that are not blood cells and is part of the extracellular fluid.
Osmosis helps to maintain the balance of water across the semi-permeable membranes of cells. The body regulates water content and osmotic balance through mechanisms such as water reabsorption during food processing in the gastrointestinal tract, the release of antidiuretic hormone (ADH) that promotes water conservation in the kidneys, and the generation of metabolic water during cellular respiration.
