Level Of Structural Organizations In Human Body

Front 1

name the 6 levels of structural organization of the human body

Back 1

1. chemical level; 2. cellular level; 3. tissue level; 4. organ level; 5. system; and 6. organismal

Front 2

chemical level

Back 2

includes atoms organized into molecules
(example: DNA, glucose)

Front 3

cellular level

Back 3

molecules are organized into cells which are the basic structural and functional living units an organism
(example: muscle cells, nerve cells, blood cells)

Front 4

tissue level

Back 4

cells are organized into tissues to perform a particular function
(example: epitheleal, connective, muscle and nervous tissues)

Front 5

organ level

Back 5

structures that are composed of 2 or more different types of tissues, that have specific functions and usually have recognizable shapes
(example: liver, stomach, heart, lungs, brain)

Front 6

system level or organ-system level

Back 6

consists of related organs with a common function
(example: digestive system, which breaks down and absorbs food, and includes the mouth, salivary glands, esophagus, stomach, small intestine, large intestine, liver, gallbladder and pancreas)

Front 7

organismal level

Back 7

all the systems are structurally integrated and function cooperatively to constitute the total organsim
(example: the human body)
