Metabolism, Anabolism, Catabolism
Sum of the body’s functions, Functions that combine small chemicals to larger, Functions that break down larger chemicals to smaller.
Excretion
Release of waste products
Responsiveness/Irritability
Sense or reaction to environmental stimuli
Movement and Reproduction
Motion, and also the ability to recreate or pass down other organisms from the parent.
Chemical Layer
First Level, from atoms to molecules.
Cellular Level
Second level, groups of molecules that have structures and functions.
Tissue Level
Third level, Groups of similar cells and extracellular matrix (outside material) that have a common purpose
Organ level
Fourth level, groups of two or more tissues that create a recognizable shape and perform a specialized function.
Organ system level
Fifth level, Body organs grouped together that carry out a broad body function (i.e. cardiovascular system)
Organism level
Sixth and last level, organ systems that work together to form a working body
