Answer: The amount of water in the human body ranges from 45-75%.1 The average adult human body is 50-65% water, averaging around 57-60%. The percentage of water in infants is much higher, typically around 75-78% water, dropping to 65% by one year of age. Body composition varies according to gender and fitness level because fatty tissue contains less water than lean tissue. The average adult male is about 60% water. The average adult woman is about 55% water because women naturally have more fatty tissue than men. Overweight men and women have less water, as a percent than their leaner counterparts. The percent of water depends on your hydration level. People feel thirsty when they have already lost around 2-3% of their body's water. Being dehydrated by just 2% impairs performance in mental tasks and physical coordination. Although liquid water is the most abundant molecule in the body, additional water is found in hydrated compounds. About 30-40% of the weight of the human body is the skeleton, but when the bound water is removed, either by chemical desiccation or heat, half the weight is lost. Most of the body's water is in the intracellular fluid (2/3 of the body's water). The other third is in the extracellular fluid (1/3 of the water).
The amount of water varies, depending on the organ. Much of the water is in blood plasma (20% of the body's total). The amount of water in the human heart and brain is 73%, the lungs are 83%, muscles and kidneys are 79%, the skin is 64%, and the bones are around 31%.

what does a positive result from a presumptive blood test mean?
Answer:
The chapter begins by recounting Lindy Chamberlain's three-decade struggle to prove that she was not guilty of slitting her baby's throat in the family car. Lindy was convicted, based in large part, on presumptive blood testing and blood tests that were thought to prove the presence of infant blood. The chapter gives an overview of the history and use of presumptive blood tests and the failures of these tests that have resulted in wrongful convictions. After describing Lindy Chamberlain's saga, the chapter is broken in to three sections: Section 1 serves as an introduction and explains why there are both presumptive and confirmatory blood tests. Part I is a thorough, basic overview of the science of testing for blood. Part II covers presumptive tests and the law, and relies on examples of cases where presumptive and confirmative testing have either been misapplied or misunderstood. Finally, Part III covers problems faced in the Lindy Chamberlain case that led to Ms. Chamberlain's wrongful conviction and incarceration.
