An Introduction to the Human Body

Two branches of science provide the foundation for understanding the body’s parts and functions

– study of the structure of body parts and their relationships to one another

. Macroscopic (Gross) anatomy – large, easily observed
. Microscopic anatomy – need microscope to observe

– study of how the body parts work or function

6 Levels of Structural Organization

Chemical (simplest) – atoms  molecules
Cellular – molecules  cells (lowest level at which life exists)
Tissue – groups of similar cells with a common function (muscle, epithelial, connective, nervous)
Organ – two or more tissues form an organ with a specific function
System – several organs form a system with a common function (11 system)
Organismal –sum total of all structural levels that together promote life of the whole organism
Genus Species : Homo Sapiens (Wise Man)

Basic Life Processes

These are the most important life processes of the human body

Metabolism – sum of all chemical processes

2 phases of metabolism
catabolism : complex substance broken down to something more simple.

5)       Differentiation – development of a cell from an unspecialized to a specialized state (ex.stem cells)

6)           Reproduction – make new cells or a new organism

7)           Excretion – remove wastes
