Human Anatomy

Human Anatomy is the scientific discipline dedicated to studying the structure and organization of the human body. As a fundamental branch of biology, it examines the body's components at every scale, from the macroscopic level of organ systems, organs, and tissues (gross anatomy) down to the microscopic level of cells (histology) and molecules. This field is intrinsically linked with physiology, the study of function, as the physical form of a structure dictates its role and capabilities within the body. A thorough understanding of anatomy provides the essential framework for all medical and health-related sciences, forming the basis for diagnosing, treating, and understanding human health and disease.
