organismal - 6 levels of structural organization
- chemical level
-
atoms
(the smallest unit of matter that participate in chemical reactions)
and
molecules
(two or more atoms joined together) - cellular level
-
the basic structural and functional unit of an organism
smallest living unit in the human body - tissue level
-
groups of cells and the materials surrounding them that work together to perform a particular function
there are 4 basis types - organ level
-
structures that are composed of two or more different types of tissues;
have specific functions
usually have recognizable shapes - system level
- consists of related organs with a common function
- organismal level
-
largest organizational level
any living individual
all parts of the human body functioning together constitute the organism - non-invasive diagnostic techniques
-
used to assess certain aspects of body structure and function
1- inspection
2- palpation
3- auscultation
4- percussion - inspection
-
non-invasived diagnostic technique
examiner observes for any changes that deviate from normal -
palpation
palp=gently touching -
non-invasived diagnostic technique
examiner feels body surface with hands -
auscultation
auscult=listening -
non-invasived diagnostic technique
examiner listens to body sounds to evaluate
often uses a stethoscope to amplify sounds -
percussion
percus=beat through -
non-invasived diagnostic technique
examiner taps on the body surface with the fingertips and listens to the resulting echo -
epithelial tissue
connective tissue
muscular tissue
nervous tissue - four basic types of tissue
