Document Summary
Water, acids, bases and buffers lecture 2. Preforms many functions: transport, component of chemical reactions, control of body temperatures. Adipose tissue holds little water, so people who are obese have less water, children have more. Total body water makes up 40l: 25l of the 40l tbw is found within the intracellular fluid (icf, 15l of the 40l tbw is found with the extracellular fluid (ecf) Within the ecf, 10l of the water is interstitial, and 5l is blood. Issues will occur, if the water from a compartment shifts into a different compartment. Shared electrons of the h-o bond are attracted to the oxygen molecule, this gives the hydrogen atoms a partial positive charge and the oxygen a partial negative charge (gaining electrons) Because of the weak hydrogen bonds, water becomes a solvent meaning it is able to break and reform. The polarity of water allows polar molecules to dissolve.
