Body water ocular fluids. Adipose tissue contains about 10% of water, while muscle tissue contains about 75%. In "Netter's Atlas of Human Physiology", body water is broken down into the following "compartments:" Total body water can be determined using Flowing afterglow mass spectrometry measurement of deuterium abundance in breath samples from individuals. A known dose of deuterated water (Heavy water, DO) is ingested and allowed to equilibrate within the body water. The FA-MS instrument then measures the deuterium-to-hydrogen (D:H) ratio in the exhaled breath water vapour. The total body water is then accurately measured from the increase in breath deuterium content in
