Histology is the study of the microscopic anatomy of parts of organisms after death (autopsy) or removal by surgery (biopsy). Tissue is fixed by agents that denature proteins, preventing autolysis and bacterial degradation; they are stained by dyes that have particular affinity for different structures. Histology facilitates the study both of normal tissue and of diseased organs, or pathological tissue.
