This document provides an overview of basic human anatomy concepts and classification. It begins by defining anatomy and physiology, with anatomy describing the parts of the organism and physiology explaining how those parts interact functionally. It then discusses the different levels of anatomical classification from cellular to organic to systemic. Several examples of anatomical divisions and views of the body are also presented, including sagittal, frontal, and transverse views. The four basic tissue types - epithelial, connective, muscular, and nervous - are introduced along with some examples. Key body cavities and a basic overview of the main internal organs are also summarized.
