|---|---|
| Anatomy | th study of the structre and shape of the body and body pats and their relationships to one another |
| Physiology | study of how the body and its parts work or function (physio=nature; ology= the study of) |
| atoms | tiny building blocksof matter which combie to form molecules |
| cells | smallest units of all livingthings |
| tissus | consist of groups of similar clls hat hav common function |
| organ | structure that is composed of two ormore tissue types and performs a specific function for the body |
| organ system | group of organs that cooperate to accompish a common purpose |
| organism | represents the highest level of structural organization |
| organ systems(11) | 1.integumentary 2.skeletal 3.muscular system 4.nervous system 5.endocrine system 6.cardiovascular system 7.lymphatic system 8.respiratory system 9. digestive system 10. urinary system 11. reproductive system |
| necessary life functions(8) | maintaining boundaries, movement, responsiveness (or irritabiliy), digestion, metabolism, excretion,reprodution, growth |
| survival needs (5) | nutrents, oxygen, water, body temperature, atmospheric pressure |
| homeostasis | describes the bodys ablity to maintain reltively stable internal conditins even though the outside world is continously changing |
| negative feedback mechanisms | decrease stimulus; more common |
| positive feedback mechanisms | increase stimulus; rarer |
| anatomical position | to avoid confusion, it is always assumed that the body is in a standard position; face front, body is erect with feet parallel and the arms hanging at the sides with the palms facing foward |

| midsagittal or median section | cut made down the median plane of the body and the right and left parts are equal in size |
| frontal section | cut made along a lengthwise plane that divides the boy into posterior and anterior |
| coronal section | =frontal section |
| transverse section | cut made along a horizontal plane, dividing the body or organ into superior an inferior parts (this = cross section) |
