Metabolism
sum of the chemical reactions that drive life functions
In metabolism you either make things or break things. This is called what?
Anabolism and Catabolism
Anabolism
building large molecules from small molecules
Catabolism
Breaking large molecules into small molecules
Describe the function of Anabolism
uses energy to make a more complex molecule
Chemical Level
the atoms and molecules that make up the basic components of the cell
Cellular Level
the basic building blocks of tissues. Cells have distinct functions with their respective unique position with the body.
Tissue Level
Made up of similar cells with a common function
What are the four basic tissue types
Epithelial, Muscle,Connective,Nervous
Organ Level
two or more tissue types that perform a specific function for the body that no other organ can preform
System Level
multiple organs that work together to accomplish a common purpose
Organismal level
represents the sum total of the structural levels working together to promote life
All cells begin as
Stem cells
Epithelium tissue function
Covering
Connective tissue function
Support
Muscle tissue function
Movement
Nervous tissue function
Control
Three types of muscle tissue
Skeletal , Cardiac, Smooth
Describe skeletal muscle
voluntary , locomotion
Describe cardiac muscle
involuntary, muscle of the heart
Describe smooth muscle
involuntary, muscle of hollow organs
Nervous tissue function
control or regulate other tissues
Two cell types of the nervous tissue
Neurons, Glial cells
Neurons function
Communication
