Functional anatomy is a branch of anatomy that focuses on the study of the structure of living organisms and how their parts function together to perform specific tasks. This field examines the relationship between the structure of different body parts and their functions in various biological processes such as movement, digestion, respiration, and circulation. Functional anatomy also explores how organs and systems work together to maintain the body's overall health and homeostasis. Researchers in this area utilize various scientific techniques such as dissection, microscopy, imaging, and computer modeling to study the structure-function relationships within organisms.
