For instance, more protein is inside cells than outside and more chloride anions exist outside of cells than inside. The composition of solutes differs between the fluid compartments. The extracellular water compartment is subdivided into the spaces between cells (interstitial), blood plasma, and other bodily fluids (such as cerebrospinal fluid which surrounds and protects the brain and spinal cord). In the human body, water and solutes are distributed into two compartments: inside cells, called intracellular, and outside cells, called extracellular. refers to all dissolved substances in a fluid, which may be charged, such as sodium (Na +), or uncharged, such as glucose.

Solutes Any dissolved substances in a fluid. For example, in water sodium chloride (the chemical name for table salt) dissasociates into sodium cations (Na +) and chloride anions (Cl −). Positively charged electrolytes are called cations and negatively charged electrolytes are called anions. are substances that, when dissolved in water, disassociate into charged ions. Electrolytes Substances that when dissolved in water disassociate into charged ions. 7 (1996): 495–502.Īlthough water makes up the largest percentage of body volume, it is not actually pure water but rather a mixture of cells, proteins, glucose, lipoproteins, electrolytes, and other substances. “Relationship of Food Groups and Water Intake to Colon Cancer Risk.” Cancer Epidemiol Biomarkers Prev 5, no. Additionally a study conducted at the Fred Hutchinson Cancer Research Center in Seattle found that women who drank more than five glasses of water each day had a significantly decreased risk for developing colon cancer. But, we do know that dehydration accelerates the aging process whereas keeping hydrated decreases headaches, muscle aches, and kidney stones.

Does the loss in body water play a role in the aging process? Alas, no one knows. This also means that if a person gains weight in the form of fat the percentage of total body water content declines.) As we age total body water content also diminishes so that by the time we are in our eighties the percent of water in our bodies has decreased to around 45 percent. (This gender difference reflects the differences in body-fat content, since body fat is practically water-free. Adult males typically are composed of about 60 percent water and females are about 55 percent water. Fortunately, humans have compartmentalized tissues otherwise we might just look like a water balloon! Newborns are approximately 70 percent water. An adult consists of about 37 to 42 liters of water, or about eighty pounds.
