In this chapter, you have learned about the basic structures of the cell to the many complex systems of the human body. In addition, you have acquired the understanding of how each body system functions and how each system is interdependent upon each other. You will use this knowledge of human anatomy and physiology throughout your career in the medical services. For example, the anatomical terminology will be used in describing location of injuries or conditions. Also, when you perform patient assessments, a clear and thorough understanding of anatomy and physiology is essential. Patient assessment and documentation procedures will be discussed in the next part, entitled “Fundamentals of Patient Care.”
