2.54 cm = 1 inch (about 2.5 to 1)
kg to lb , g to lb
1 kg = 2.2 lbs 453.6 gm = 1 lb

Anatomy
Morphology = study of structure
Gross anatomy
the study of non-microscopic structures
2 types of Anatomy
Systemic Anatomy or Regional Anatomy
Embryology
developmental anatomy
Neuroanatomy
the study of the cellular organization of the brain and spinal cord
Histology
study of tissues
Cytology
study of cells
Levels of structural organization (6)
A) Chemical level - atoms, molecules, etc.
B) Cellular level - basic structural and functional units of our bodies.
C) Tissue level - groups of similarly specialized cells that perform special functions = tissue example: pseudostratified ciliated columnar epithelium.
D) Organ level - Organ = structure made up of two or more tissues which performs a specific function in the body.
E) System level - an association of organs having a common function.
F) Organism - all parts of the body functioning in cooperation with one another = the individual, you and I.
