General Anatomy and Physiology is a comprehensive textbook designed for community and technical college students, examining the basic concepts of human anatomy and physiology as they relate to health sciences. Using a body systems approach, the book emphasizes the interrelationships between structure and function at both the gross and microscopic levels of organization. It covers essential topics such as anatomical terminology, cellular biology, tissue organization, and the functions of major systems, including the integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, respiratory, digestive, urinary, and reproductive systems. This textbook is intended to prepare healthcare professionals to apply foundational knowledge of anatomy and physiology to informed decision-making and effective communication with colleagues and patients. With a blend of theoretical concepts and practical applications, it serves as a vital resource for students pursuing careers in health sciences and provides the foundation for advanced studies in the field.
