What does histology study?

Histology is the branch of biology that focuses specifically on the study of the cellular structure of tissues. This field examines how cells are organized in various tissues, allowing for a deeper understanding of how these tissues function and how they contribute to the body's overall physiology. Histology is critical for identifying the characteristics of normal and diseased tissues, as it provides insights into the cellular organization that supports different functions in living organisms. Understanding histology is essential for professionals in healthcare, including those working in fields such as pathology, where tissue samples are analyzed for diseases.

Studying the cellular structure of tissues involves looking at how different types of cells are arranged and how they interact with one another, which lays the foundation for understanding more complex biological systems. This specialization is distinctly different from examining the functions of various bodily systems, the overarching structures of living organisms, or the biochemical processes that occur within cells. Each of those areas emphasizes different aspects of biology that do not directly correspond to the focus of histology.
