Which of the following is the standard reagent used for the dehydration of tissues?
Show answer and explanation
Correct answer: Graded ethanol series
Dehydration is achieved by passing the tissue through a series of increasing concentrations of alcohol (usually 70% to 100% ethanol). This gradual process ensures that water is removed without causing excessive tissue shrinkage or distortion.
