A: A group of tissues that work together to perform a specific function is called an organ. The human body has many organs, and each has its own specific function. In some cases, groups of organs also work together to serve a larger function, and this is known as an organ system.
Although each organ (see Tissues and Organs) has its specific functions, organs also function together in groups, called organ systems (see Table: Major Organ Systems). Doctors categorize disorders and their own medical specialties according to organ systems, and this book also is structured largely around the concept of organ systems.
