Flammable chemicals are essential in histology for various reasons:
Fixation: Chemicals like formaldehyde are used to preserve tissue samples by cross-linking proteins, which prevents decay and maintains the sample's structure. Dehydration: Ethanol is commonly used to remove water from tissue samples, making them easier to embed in paraffin wax. Clearing: Xylene is used to make tissues transparent, allowing for better visualization under a microscope.
