Organizational structure of body Flashcards
The simplest level of the structural hierarchy
chemical level
what happens at the chemical level
atoms combine to form molecules
Molecules in turn form what
organelles
what are the basic components of the microscopic cells
organelles
smallest unit of living things
cells
groups of similar cells that have a common function
tissue
What is the organization structure of the body
chemical level (atoms, molecules, organelles) cellular level (cells) tissue level (tissue) organ level (organ) organ system level organismal level (human being)
The highest level of organization
living human being
extremely complex functions become possible in this level
organ level
organs that work together to accomplish a common purpose make up this system
organ system level
represents the sum total of all structural levels working together to keep us alive
organismal level
more than one tissue type that performs a specific function for the body makes up an organ.
organ system level
groups of similar cells which have a common function. There are four different tissue types in the human body: epithelial (skin) muscle connective (ligaments) nervous tissue
Tissue level
