Water

The Most Essential Nutrient -Jaelyn Powell

Water


  • Water is the most abundant constituent of the body, accounting for 50% to 60% of its mass. It is an inorganic (contains no carbons) substance composed of two hydrogen atoms which are bonded to one oxygen atom. Water is intricately involved in numerous functions of the body including the transport of oxygen, nutrients and waste products into and out of the cells. Drinking water contains several electrolytes (substances in solution that conduct an electric current) including calcium, chloride, fluoride, magnesium, potassium and sodium. Even though it contains no calorie content, water is the medium for most chemical reactions in the body, especially those metabolic reactions involved in energy production. The body uses water as a coolant, helping to regulate body temperature during exercise, fever and in hot environments. Water also serves as a cushioning component between joints, in the spinal cord and in the brain. http://www.unm.edu/~lkravitz/Article%20folder/WaterUNM.html
