Anatomy
Study of body structures and their relationships to each other
Gross anatomy
Study of the relatively large structures that are usually visible with the unaided eye e.g organs
Microscopic anatomy
Study of structures that need magnification to be viewed e.g tissues and cells
Physiology
The study of how the body normally functions (i.e in the non-diseased state)
Organism

System

Cells
The basic structural unit of an organism (made of molecules)
Molecules

Levels of human Structure (most complex to least)
Chemical Cellular Tissue organ Organ system Organismal
Chemical level
Atoms joining to make molecules
Cellular level
Molecules combining to make cells
Tissue level
Groups of cells and the material that surrounds them combining to form tissues
Organ system level
Organs connecting that serve a common function are called an organ system
Organismal level

6 Characteristics of a living organism
Metabolism Responsiveness Move Growth Differentiation Reproduction
Metabolism
The sum of chemical processes that happen in the body
Responsiveness
The bodys ability to detect and respond to changes
Move
A change of place, position or state
Growth
An increase in body size either from cells getting bigger or an increased number of cells
Differentiation
The process where you start with one type of cell and that cell then subsequently turns into another type of cell
Reproduction
Making new cells for either growth, repair, replacing old ones that you have lost of creation of a new organism
