Answer:B The nervous system controls the speed at which food moves through the digestive system
Explanation:During digestion,the nervous system helps to control the actions that takes place.they stimulate digestive juices and the muscles of digestive organs.
The extrinsic nerves comes to the digestive tract from the brain and the spinal cord.they release chemicals; acetylcholine and adrenaline.
Acetylcholine causes the muscles of the digestive organs to squeeze and push the food through the tract.adrenaline relaxes the muscles and reduces blood flow to the organs.these occurs unconsciously.
The intrinsic nerves acts to speed up or delay the movement of food in the digestive tract and also the production of digestive juices.
