Key Differences
Anatomy is the branch of biology concerned with the study of the structure of organisms and their parts. It delves into the physical structures, or morphologies, of body parts, including their shapes, sizes, and compositions. Whereas physiology examines the functions and processes of the body's components, exploring how bodily parts operate and work together to sustain life.
While anatomy provides a detailed mapping and naming of various parts of an organism, such as organs, muscles, and bones, physiology brings insight into the biochemical, physical, and mechanical functions of these parts. For instance, anatomy will detail the structure of the heart, whereas physiology explains how the heart pumps blood throughout the body.
Anatomy is often divided into subcategories such as gross (macroscopic) anatomy, which includes structures visible to the naked eye, and microscopic anatomy, which involves the use of microscopes to see finer details not observable by the naked eye. On the other hand, physiology covers broad areas, including cellular physiology, which focuses on cell function, and systems physiology, which looks at the function of specific organ systems.
Studying anatomy involves techniques and approaches such as dissection and imaging technology to visualize the interior of the body, providing a static picture of bodily structures. Physiology, however, employs experiments, measurements, and simulations to understand dynamic processes, such as nerve impulses or blood circulation, highlighting the functional aspects of the body.
Both anatomy and physiology are foundational to the medical and biological sciences, offering complementary perspectives on the human body. Understanding anatomy is crucial for identifying parts of the body and their relationships, while knowledge of physiology is essential for comprehending how those parts function and contribute to overall health and disease states.

Anatomy
Anatomy (Greek anatomē, 'dissection') is the branch of biology concerned with the study of the structure of organisms and their parts. Anatomy is a branch of natural science which deals with the structural organization of living things.
Physiology
Physiology (; from Ancient Greek φύσις (physis) 'nature, origin', and -λογία (-logia) 'study of') is the scientific study of functions and mechanisms in a living system. As a sub-discipline of biology, physiology focuses on how organisms, organ systems, individual organs, cells, and biomolecules carry out the chemical and physical functions in a living system.
