what is the differance of systematic and regional anatomy?

anatomy studies the bodily structure 

systematic studies the body by organ systems

regional studies the bodies by areas

true "to cut apart" 

levels of organization


chemical,(atoms & molecules) cellular (nucleus &mito), tissue(groups of simmilar cells), organ(2 or more tissues with same function), organ system and organism

there are 11 organ systems
integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, lymphatic, repiratory, digestive, urinary and reproductive
classify the four primary tissue types
epithelial connective nervous and muscular

the chart of life


organization metabolism responsiveness growth development and reproduction

homeostasis requires three things


receptor-todetect changes

control center-to determine set point

effector to respond tp change  

negative feedback

positive feedback 

common, 2 maintain H 

Rare, change is increased (BAD) example is bleeding and cloting  

Vertical divides the body into
anterior and posterior

the primary cavity

and what does it contain 

Dorsal it contains the brain and the spinal cord

matter has weight and occupies space

what else is matter composed of  

composed of elements which is the smallest unit of matter

no 2 elements have the same atomic number  

the atomic number of hydrogen is what 

oxygen has 8 protons so the atomic # is 



what are the three types of sub atomic particles?

what is inside the central neucleus? 

which one is in the orbital shell? 

proton neutron and electron

protons and neutrons 

electrons are in the orbital shell 

how many electrons are full in the inner orbital?

the second orbital can hold up to how many? 

the third orbital can hold up to how many? 




the outermost orbital with any electrons
which is never lost or gained, proton or electron?
protons are never lost or gained
two or more elements in a fixed ration is a
compound ex is h20
three types of chemical bonds

ionic: transfer electrons between atoms

covalent: electrons shared between atoms

hydrogen :form weak attractions and R easily broke by temp or ph


atoms that gain are what charge

atoms that loss are what charge 

gain are negative charge (anion)

LOSE are positive charge (cation) 

these bonds are common in inorganic molecules 

Covalent bond common in what kind of molecule


represent stored energy


dehydration synthesis is an exaple of a chemical reaction

water released as bond formed-this takes energy

example of glycogen from glucose 

example of synthesis

makes a larger molecule


example of decomposition

breaks bonds and releases energy


this is the reverse of dehydration synthesis 



bonds are broken and formed

involves synthesis and decomposition 

4 Organic molecules that contain carbon

carbohydrates (ch20)n quick source of energy

lipids moving things in & out of cell long term energy

proteins composed of amino acids and carries stuff

nucleic acids (animal DNA) 

proteins are composed of amino acids joined by what type of bond

how many amino acids


peptide bond


structure, carries, enzymes, hormones, antibodies buffers


human skull has 8 cranial bones joints known as sutures and foramena serve as passageways for blood vessels and nerves

and 14  facial bones that form the underline structure

sphenoid bone makes up the anterior base of the cranium.
