What is the distribution of fluid throughout the body?
In the body, water moves constantly into and out of fluid compartments as conditions change in different parts of the body. For example, if you are sweating, you will lose water through your skin. Sweating depletes your tissues of water and increases the solute concentration in those tissues.

Oct 3, 2022 · Several principles control the distribution of water between the various fluid compartments. To understand the different principles, it is essential to realize that ingestion and excretion of water and electrolytes are tightly regulated to maintain consistent total body water (TBW) and total body osmolarity (TBO).

Water content in the body can be evaluated using bioelectrical impedance and mass spectrometry. Important functions of water in the body include supporting the cellular metabolism, molecular transport, biochemical reactions, and the physical properties of water, such as surface tension.
Jan 27, 2023 · The distribution of fluid throughout the body can be broken down into 2 general categories: intracellular fluid and extracellular fluid. Intracellular fluid is approximately 40% of the total body weight. It is the total space within cells primarily defined as the cytoplasm of cells.

- Body Water Content. Human beings are mostly water, ranging from about 75 percent of body mass in infants to about 50–60 percent in adult men and women, to as low as 45 percent in old age.
- Fluid Compartments. Body fluids can be discussed in terms of their specific fluid compartment, a location that is largely separate from another compartment by some form of a physical barrier.
- Composition of Body Fluids. The compositions of the two components of the ECF—plasma and IF—are more similar to each other than either is to the ICF (Figure X.4).
- Fluid Movement between Compartments. Hydrostatic pressure, the force exerted by a fluid against a wall, causes movement of fluid between compartments. The hydrostatic pressure of blood is the pressure exerted by blood against the walls of the blood vessels by the pumping action of the heart.
Water is the main component of the human body; it is distributed throughout the body, in every organ, inside and between cells. I.1. Water content of the human body. I.1.1. Total body water. Water represents on average 60% of the body weight in adult men, and 50-55% in women (EFSA 2010; IOM 2004).
