The Tissue processing involves a series of steps to prepare biological samples for microscopic analysis. First, fixation preserves the tissue's structure and prevents decay. Dehydration removes water, followed by clearing to render the tissue transparent.  Infiltration replaces the solvent with a supporting medium like paraffin.  Embedding positions the tissue in the medium for sectioning.  Thin sections are cut using a microtome and mounted on slides.  Staining highlights cellular structures and components.  Finally, coverslips are added with mounting medium.  These steps enable researchers to study tissue morphology and pathology under a microscope.
