Anatomy and Physiology

The human body is a complex and well-organized structure made up of cells, tissues, organs, and systems working together to maintain life. It includes major systems such as the circulatory, respiratory, digestive, nervous, musculoskeletal, and reproductive systems. Understanding the structure (anatomy) and function (physiology) of these systems is essential in nursing to provide effective care, identify abnormalities, and support recovery and health maintenance.
