Muscle tissue stores the greatest quantity of body water due to its high water content, which is essential for maintaining cellular functions, facilitating nutrient transport, and supporting metabolic activities. Muscle cells, or myocytes, are composed of approximately 75% water by weight, making them a significant reservoir of body fluids. This high water content is crucial not only for muscle function but also for overall hydration and homeostasis in the body.

Adipose tissue, while it does contain some water, has a much lower water content compared to muscle. It is primarily designed for energy storage and insulation rather than fluid retention. Bone tissue has a relatively small amount of water as it serves structural and protective roles. Connective tissue also contains some water, but it is not as abundant as in muscle tissue. Thus, muscle stands out as the primary tissue responsible for storing the largest amount of body water.
