Answers
Explanation:
Although each organ 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.
Some examples of organ systems and their functions include the digestive system, the cardiovascular system, and the musculoskeletal system.
The digestive (or gastrointestinal) system, extending from the mouth to the anus, is responsible for receiving and digesting food and excreting waste. This system includes not only the stomach, small intestine, and large intestine, which move and absorb food, but associated organs such as the pancreas, liver, and gallbladder, which produce digestive enzymes, remove toxins, and store substances necessary for digestion.
The cardiovascular system includes the heart (cardio) and blood vessels (vascular). The cardiovascular system is responsible for pumping and circulating the blood.
The musculoskeletal system includes the bones, muscles, ligaments, tendons, and joints, which support and move the body
