What is the study of the configuration or structure of living organisms called?

The study of the configuration or structure of living organisms is referred to as morphology. This field encompasses both the form and structure of organisms, including their external shapes and internal structures. Morphology can be applied at various levels, from cellular structures to anatomical systems in organisms.

While anatomy also pertains to the structure of organisms, it typically focuses more on the physical structures and systems within a particular organism rather than the broader concept of form and structure that encompasses all living entities. Histology, on the other hand, specifically refers to the microscopic structure of tissues, and physiology studies the functions and processes of living organisms, rather than their shapes or configurations. Therefore, morphology is the most accurate term for the study of the configuration or structure of living organisms.
