water - ANSWER--an inorganic molecule
-60-80% of the volume of living cells
-chemical nature gives it 6 important properties
water is the universal solvent - ANSWER-water is polar- and allows small reactive
compounds and ions to dissociate evenly (blood plasma, water in the lungs, bodily
secretions and excretions)
-hydrophilic
-hydrophobic
hydrophilic - ANSWER-substances that dissolve in water
hydrophobic - ANSWER-substances that repel water
adhesion - ANSWER-tendency of one substance to cling to another
serous fluid - ANSWER-creates lubrication
cohesion - ANSWER-tendency of molecules of the same substances to cling to each
other
-forms surface tension
chemical reactivity - ANSWER-water can ionize acids and salts, and can dissociate into
H+ and OH-
, hydrolysis - ANSWER-dissociate of a water molecule breaks a chemical bond in
another molecule
dehydration synthesis - ANSWER-formation of a water molecule forms the bond
between two other molecules
high heat capacity - ANSWER-the amount of heat required to raise the temperature of 1
gram of a substance by 1 Celsius
high heat of vaporization - ANSWER-large amounts of heat are required to evaporate
water
pH units - ANSWER-the relative concentration of H+ ions (expressed as moles/ liters)
pH - ANSWER-the direct measure of the number of free-floating hydrogen ions present
in the body fluids
what is the normal pH range of blood? - ANSWER-7.35-7.45
How does the body maintain a normal pH? - ANSWER-acids and bases can react to
form water and salt
-the body produces buffers
buffers - ANSWER-resist abrupt and large swings in the pH of body fluids
-renal and the respiratory systems are crucial for buffering pH swings in the blood
organic compounds - ANSWER-compounds containing Carbon
-usually large
-carbon is electronneutral so it always forms covalent bonds
functional groups - ANSWER-reactive parts
