Systemic anatomy

We’ve covered regional anatomy, dividing our body into discrete areas. However, the human body also consists of physiological systems that span multiple regions and are composed of many anatomical structures. Systemic anatomy, the second branch of human anatomy, subdivides the body into discrete organ systems that work together towards a common goal or function. The ten systems are called integumentary, musculoskeletal (skeletal, muscular), nervous, endocrine, circulatory, respiratory, digestive, urinary, reproductive, and lymphatic.

In contrast to its previous counterpart, the systemic approach divides studying into areas dealing with specific functions rather than locations or proximity. This approach covers anatomy from a more physiological perspective, studying structures that accomplish one body function together. For example, the nervous system covers all nerves in the body, which span different regions from the brain to the lower limb.
