The study of structure and form
Examination of larger structures that's visible to the eye
What are some examples of gross anatomy?
Regional, comparative, systemic surface, embryology
Examination of structures that require magnification to be seen
What are some examples of microscopic anatomy?
Study of function
What are characteristics of a living organism?
Organization, metabolism, growth and development, responsiveness, regulation, reproduction
Have complex structure and order
Can carry out chemical reactions
Why do living organisms reproduce?
Growth, maintenance, repair, production of offspring
What are the levels of organization? (smallest to largest)
Chemical, cellular, tissue, organ, organ system, organism
Smallest unit of matter exhibiting characteristics of an element
Combination of atoms
Functions of atoms are determined by ____ and ____
3D shape and atomic composition
Microscopic structures in cells for specialized functions
Smallest unit of life
What are the basic principles of the cell theory?
Cells are structural building blocks, cells come from pre-existing cells, smallest structural units which perform vital functions
Groups of cells working together for a specific function
What are the 4 types of tissues?
Epithelial, muscle, nerve, connective
Two or more tissues working together
Organs working together
What is the function for the cardiovascular system?
Breathing; gas exchange

Closer to the surface
Further from the surface
Closer to the trunk of attachment
Further from the trunk of attachment
Vertical plane that separates anterior from posterior
Vertical plane down the midline dividing the body into equal left and right parts
Does not directly run down midline dividing body into unequal left and right parts
Plane is perpendicular to the long axis and separates superior from inferior
Ability to maintain consistent internal environment
Sensor which is sensitive to a particular environmental change or stimulus
Receives and processes information supplied by the receptor and sends out commands
Responds to commands given by control center
Effector activation opposes or negates the original stimulus; make it opposite
Stimulus is reinforced until a climatic event occurs; keeps going
What is an example of negative feedback?
Being too cold, then you warm up
