exploratory surgery is
open up the body and talking a look inside to see what was wrong and what could be done about it.
the study of the structure and function of individual cells
take a tissue sample, thinly sliced and stain them to observe them under a microscope. (microscopic anatomy).
define gross anatomy
structures that can be seen with the naked eye by observation, radiology, or dissection.
-name the medical imagery that penetrates tisues to darken photographic film beneath the body.
-Dense tissue appears white
name the medical imagery that injects or swallows radiopaque substance. fills hallow structures, blood vessels, and intestinal tracts.
name the medical imagery that uses low-intensity x-rays and comuter analysis.
-slice-type images, and increases sharpness of image.
Computed tomography or CAT scan
name the medical imagery that assesses metabolic state of tissues, distinguishes tissues most active at a given moment.
-mechanics-inject radioactively labeled glucose.
-image color shows tissues using the most glucose at that moment, and damaged tissues appear dark.
