Water
|
Largest single component in the body
45%-75% of body’s total weight 2/3 of body fluid is intracellular Bones are almost 1/3 water Muscles and brain cells are 70% water Fat – no water! |
|
|
2 Main Functions of water
|
Solvent for essential nutrients so can be used by body
Transport nutrients and oxygen from blood to cells, and remove waste from cells to blood to be excreted Other functions include Give shape and form to cells Regulate body temperature Lubricant in joints Cushion body organs |
|
|
Water loss has negative effect on body function
|
2%-5% water loss = 30% decrease in work performance
