    • 1.1: Overview of Anatomy and Physiology
      This page discusses the essential principles of human anatomy and physiology, emphasizing their interconnectedness. Anatomy examines body structures, divided into gross and microscopic categories, using dissection and imaging for study. Physiology focuses on the functions of these structures and the body's mechanisms, with a strong emphasis on homeostasis. It encourages linking anatomical form to physiological function, using the human hand's structure and capabilities as a key example.
    • 1.2: Overview of the Scientific Method
      In simple terms, biology is the study of living organisms and their interactions with one another and their environments. This is a very broad definition because the scope of biology is vast. Biologists may study anything from the microscopic or submicroscopic view of a cell to ecosystems and the whole living planet.
    • 1.3: Structural Organization of the Human Body
      This page explains the six levels of organization in the human body, highlighting cells as the fundamental units of life. It describes the roles of tissues, organs, and organ systems, including their interactions, and introduces the eleven organ systems. The page also differentiates biological sex from gender identity, clarifying relevant terminology. This foundational knowledge is essential for comprehending human anatomy and physiology.
    • 1.4: Homeostasis
      This page details homeostasis and its regulatory mechanisms, particularly negative and positive feedback systems. Negative feedback maintains physiological parameters like body temperature and blood glucose by reversing deviations. It outlines the components of negative feedback systems, including sensors, control centers, and effectors, with examples like temperature regulation.
    • 1.5: Anatomical Terminology
      This page provides essential anatomical concepts for understanding the human body, highlighting the significance of anatomical position, directional terms, and body planes for clear medical communication. It distinguishes between anterior and posterior body cavities and explains serous membranes' protective roles. Additionally, it defines sagittal, frontal, and transverse planes crucial for interpreting medical imaging body sections.
