1. ANATOMY AND PHYSIOLOGY CHAPTER 2 CONCEPTS “I was taught that the way of progress is neither swift nor easy.” Marie Curie

2. WATER • UNIVERSAL SOLVENT • CELLS REACT DIFFERENTLY TO WATER • HYDROPHOBIC • HYDROPHILIC • MIXTURES • SOLUTIONS – SOLUTE, SOLVENT • SUSPENSIONS - COLLOIDS

3. CHEMICAL BONDS • IONIC – ‘DONATED’ THE ELECTRON • THIS IS THE BOND TYPE OF OUR BODY’S ELECTROLYTES; ELECTROLYTE SOLUTIONS CARRY AN ELECTRICAL CHARGE (IE, EKG) • COVALENT – SHARE AN ELECTRON • VOCABULARY: IONIC, ANION, CATION

4. THE pH SCALE • POTENTIAL OF HYDROGEN • NEUTRAL IS 7 BASED UPON DISTILLED WATER • THE MORE HYDROGEN (H+) THERE IS, THE MORE ACIDIC THE SUBSTANCE; THE NUMBER IS DECREASED AWAY FROM NEUTRAL. • THE LESS H+, THE HIGHER THE NUMBER ON THE SCALE = ALKALINE • SERUM LEVEL 7.35- 7.45

5. CHEMISTRY OF LIVING MATTER • HONC - THE 4 MAIN ELEMENTS IN YOUR BODY • OYGEN IS MOST PREVALENT • ORGANIC COMPOUNDS – MUST CONTAIN CARBON (C) • CH20 – CARBOHYDRATES, LIPIDS, PROTEINS • INORGANIC COMPOUNDS – DO NOT CONTAIN CARBON

6. MEDICAL TERMINOLOGY • HYDR/O- • -PHIL • -PHOBIA • HOM/O- • HETER/O- • AQU/E- • DI- • MON/O- • TRI- • -ASE • DE- • GLYC/O-
