Definitions of Chapter 1 Flashcards
Dissection
The carful cutting apart of body structures to study their relationships.
Physiology
Deals with functions of body parts - that is, how they work.
Noninvasive Diagnostic Technique
One that does not involve insertion of an instrument or device through the skin or into a body opening.
Inspection
The first noninvasive diagnostic technique, the examiner observes the body for any changes that deviate from normal.
Palpation
The examiner feels body surfaces with the hands.
Auscultation
The examiner listens to body sounds to evaluate the functioning of certain organs, often using a stethoscope to amplify the sounds.
Percussion
The examiner taps on the body surface with the fingertips and listens to the resulting sound.
Chemical Level
Can be compared to the letters of the alphabet, includes atoms, and molecules.
Atoms
The smallest units of matter that participate in chemical reactions.
Molecules
Two or more atoms joined together.
Cellular Level
Molecules combine to form cells, which can be compared to assembling letters into words.
Cells
Structures composed of chemical and are the basic structural and functional units of an organism. Just as words are the smallest building blocks of language, cells are the smallest living units in the human body.
Tissue Level
The second level of structural organization.
Tissues
Groups of cells and the materials surrounding them that work together to perform a particular function, similar to the way words are put together to form sentences.
Organ Level
Different types of tissues are joined together.
