Document Summary

Subdivisions: gross anatomy visible to eye e. g bones, microanatomy microscope required e. g. cytology study of cells cytologist studies internal structures of cells histology study of tissues. Levels of organizations: chemical level atoms e. g. h&o atoms atoms combine forming molecules e. g. water, cellular level molecules form organelles which form cells cells: basic unit of structures & function, tissue level group of cells with similar structure. Resulting chemicals may be: organic covalently bonded carbon atoms e. g. proteins b. inorganic lack of carbon e. g. h2o, nacl, o2 exceptions: h2co3 (carbonic acid) Carbohydrates naming: monosaccharides (simple sugars) e. g. glucose, fructose, ribose, deoxyribose, disaccharides ( 2 mono covalently bonded) e. g glucose + fructose = sucrose, polysaccharide (many mono bonded together) e. g. glycogen animals starch plants, lipids c, h, o ratio different from carbohydrates e. g. fats, oils , waxes, fatty acids (fa) insoluble (non polar) in h2o.
