उत्तर
The neurological and hormonal systems control the actions of the gastrointestinal tract, sometimes known as the "GI- tract." The GI tract is connected by several intrinsic and extrinsic nerves. These nerves aid in the regulated working of the alimentary canal's numerous components. Furthermore, several hormones are involved in the coordination of these processes.
