Which scientific discipline studies the structure and function of tissues?

Histology is the scientific discipline focused on the study of tissues, including their structure, organization, and function at the microscopic level. It involves examining the various types of tissues—such as epithelial, connective, muscle, and nervous tissue—under a microscope to understand how they contribute to the overall functioning of organs and systems in the body. Histologists analyze the cellular composition and how different cells interact within tissues, which is essential for understanding both normal physiology and pathological processes.

In contrast, pathology examines diseases and their effects on tissues and organs, while cytology is the study of individual cells, not tissues. Physiology, on the other hand, deals with the functions and processes of various systems in the body, but it does not specifically focus on the tissue structure itself. Thus, the correct answer is based on histology's dedicated focus on tissues, which is foundational in various fields, including medicine and cosmetology.
