What Are the Human Organ Systems?
There are eleven essential organ systems in the human body, but five of these organ systems that help us tremendously in maintaining things and help keep us going. The nervous system allows us to sense the world around us and inside of us. The brain works as the control center of the nervous system. It is located within the skull. A brain muscle's function is to control and coordinate the sensory reception and integration, memory storage, speech production, and elaborating thoughts and emotions. The nervous system works together with our endocrine system to control our metabolism of all chemicals inside of us and regulate body functions. The circulatory system helps put life given gases into our system and remove all types of wastes. Lungs are two cone-shaped and sponge-like structures that fill most of the chest cavity. The essential function is to provide oxygen from inhaled air to the bloodstream and to exhale carbon dioxide. The heart is a muscular, hollow organ that pumps blood through repeated rhythmic contractions through the blood vessels. The digestive system allows us to take in energy and process the food that we eat. It is an elastic, muscular, pear-shaped bag, lying crosswise in the abdominal cavity under the diaphragm. Its main purpose is to digest food by producing gastric juices that break down, mix and turn the food into a thin liquid.
