Which field of study focuses on the composition and function of tissues?

The field that focuses on the composition and function of tissues is histology. Histology is a branch of biology concerned with the microscopic structure of tissues and organ systems. It involves studying the organization of cells and their relationships within tissues, and it examines how these structures contribute to the functionalities of the organs they comprise. By analyzing tissue samples, histologists can understand how cellular arrangements influence tissue behavior, aiding in research and medical diagnostics.

In contrast, while biochemistry explores the chemical processes and substances that are crucial to living organisms, it does not specifically concentrate on tissue structures. Neurology primarily deals with the nervous system and its disorders, focusing on nerve functions and brain activity rather than tissue composition. Pathology studies diseases and their effects on tissues and organs, providing insights into disease processes but not primarily on the normal function and structure of tissues themselves. Thus, histology is the most appropriate field in this context for understanding tissue composition and function.
