How do the digestive and nervous systems interact?
The digestive system actually has its own nervous system called the 'enteric nervous system' (ENS) that acts almost entirely independently of the brain. The ENS has roughly as many neurons as the spinal cord (~90 million) contained in plexuses that surround the the entire gastrointestinal tract. These include both sensory as well as motor neurons. Together they detect changes in the gut (as a result of ingesting food/drink) and regulate secretion and motility. Although the ENS is under autonomic influence - e.g. increased parasympathetic tone during sleep - the actual influence is limited. In fact the ENS will continue to function normally without any sympathetic/parasympathetic input at all.

The brain and spinal cord send messages to the heart and bloodvessels via the peripheral nervous system, specifically thesympathetic and parasympathetic divisions. The sympath…etic nervoussystem innervates the heart and causes an increases heart rate andforce of contraction; it also innervates the blood vessels and canproduce either constriction of the blood vessels or relaxation. The parasympathetic nervous system innervates the heart as well,but reduces heart rate and force of contraction. With fewexceptions, the parasympathetic nervous system does not innervatethe blood vessels. As a consequence of this innervation, the peripheral nervous systemregulates heart rate and blood pressure.
It works with the circulatory system because nutriants , vitamins, and food follow through our blood
actually the skeletal system and nervous system work with the digestive system
In the cardiovascular system, the nervous system modulates heart rate, contractile strength and vascular tone SYMPATHETIC NERVOUS SYSTEM Promotes a "fight or flight" res…ponse, corresponds with arousal and energy generation, inhibits digestion: Diverts blood flow away from the gastro-intestinal (GI) tract and skin via vasoconstriction. Blood flow to skeletal muscles, the lung is not only maintained, but enhanced (by as much as 1200%, in the case of skeletal muscles). Dilates bronchioles of the lung, which allows for greater alveolar oxygen exchange. Increases heart rate and the contractility of cardiac cells (myocytes), thereby providing a mechanism for the enhanced blood flow to skeletal muscles. Dilates pupils and relaxes the lens, allowing more light to enter the eye. PARASYMPATHETIC NERVOUS SYSTEM Promotes a "rest and digest" response; promotes calming of the nerves return to regular function, and enhances digestion. Dilates blood vessels leading to the GI tract, increasing blood flow. This is important following the consumption of food, due to the greater metabolic demands placed on the body by the gut. The parasympathetic nervous system can also constrict the bronchiolar diameter when the need for oxygen has diminished. During accommodation, the parasympathetic nervous system causes constriction of the pupil and lens. The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients. Is also involved in erection of genitals, via the pelvic splanchnic nerves 2-4. === The nervous system affects the kidneys by modifying renin secretion In addition to those visceral functions, the nervous system works with the special senses (vision, hearing), the general sense *pain and temperature sensation on the skin, body movement and position sense. It also controls the musculoskeletal sytem and connects to various glands.

The peripheral nervous system, which is responsible for sensation, coordination of muscle and organ activity, and movement, is composed of lengthy nerves. Besides interaction …with the central nervous system (brain & spinal cord), the nervous system receives input from pressure, temperature, pain, light, sound, smell, and taste.
The nervous system delivers rapid responses to the brain with regard to pain and pleasure.
The digestive and nervous system relate directly so as to performvarious body functions. The digestive system will provide nutrientsfor the nervous system while the nervous sy…stem will coordinate thecells to perform digestion.
Digestive and nervous systems are both extensive systems that covera large distance in the human body. The nervous system extends fromthe brain, down the spinal cord and conne…cts all neurons in thebody. The digestive system extends from the mouth down to theexcretory organs.
Through the hypothalamus and the pituitary gland which is found between the eyes, above the nasal cavity. In simple terms...: The hypothalamus detects low levels of a cert…ain hormone in the blood (lets say Thyroid hormone) and so releases hormone signals (called Thyroid Releasing hormone) which travel to the pituitary gland below it telling it that the body needs more of this particular thyroid hormone. The pituitary will then produce its own signalling hormone (thyroid stimulating hormone) which will travel to the organ in question (the thyroid), telling it to produce more of its own hormone (T3 and T4). Once the organ has produced an adequate amount of the desired hormone, levels of it in the blood rise. This level is picked up by the hypothalamus in turn, which sees that there is enough of this hormone in the body, and so stops sending its signals to the pituitary, reducing the production of thyroid hormone until levels fall again. Hope this helps!
The skin has specialized sensors that are imbeded into it such as: Hair follicle endings: responds to hair displacement ruffini endings: responding to pressure on the skin kr…ause corpuscle: responding to pressure on the lips or tongue Pacinian corpuscle: which responds to vibration in deep layers of dermis Messiner corpuscle: which responds to vibration in the dermis of glabrous skin or free nerve endings: which respond to mechhanical thermal or noxious stimulaiton all of these receptors pick up things from the environment and send them to the brain for perception and identification.

The autonomic nervous system controls digestive functions. It tells your body to digest your food and stimulates the muscles in your intestinal wall-- these are things over wh…ich you have no control. The nervous system also tells you when it's time to go to the bathroom.
The sinoatrial (SA) node of the heart serves as its pacemaker, and receives nerve input from the nervous system in order to initiate the "pumping" activity that controls the c…irculatory system. In addition, muscles of blood vessels can expand and contract from signals from the autonomic (sympathetic and parasympathetic) nervous system in order to control blood pressure.
