Nerve signals tell the brain what is the right thing to eat such as temperature and size and then causes saliva to be produced and moistens the food and forms the bolus which is then pushed down the throat after the CNS send the signal to contract smooth muscle…
One of the final portions of the digestive system. Includes the anal canal, rectum, colon, and cecum. Takes care of absorbing any water left in the food that hasn't been digested yet, and then passing any unused waste from the body…
The gastrointestinal tract starts with the mouth, which leads to the gullet via the stomach, small intestine, large intestine, and ends at the anus. In due course of the journey, the ingested food is broken down by both physical and chemical means to release nutrients which are absorbed into the blood stream. The ingested food is physically broken down in the mouth by chewing so as to reduce its size for increased surface area over which enzymatic reaction will take place. Enzymatic reaction is known as digestion and this is defined as the chemical breakdown of the ingested complex food molecules by the action of biological enzymes, into simplest form that can be absorbed into the blood stream and assimilated into living cells. In human beings, various components of the ingested food are digested and absorbed at various sections of the alimentary canal .…
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.…
We all love to eat. I remember my parents used to tell me that in order for my food to digest properly, I would have to chew it one hundred times on both side to make it small as possible. They said that if the food was smaller it could digest quicker and easier. But most people do not know what happens to their food after they have chewed it up and swallowed it. Some may think that right after the food is swallowed, it goes straight to the stomach. The purpose of this essay is to discuss the path food follows as it goes through the digestive system.…
Which of the following digestive regions is responsible for the propulsion of materials into the esophagus?…

The digestive system is the physical ad chemical breakdown of food. Following ingestion, food and fluids are processed by the digestive organs so that nutrients can be absorbed from the intestines and circulated around the body. Any residue of food that is not digested is solidified and eliminated from the body in the form of feces. (P.207)…

The absorbed substances are then moved through the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body. The food that remains undigested and unabsorbed passes into the large intestine where very small amounts of nutrients are absorbed. The food then exits your body through the rectum or anus.…
Tongue: It’s supplied with a number of muscular valves. That control and direct the amounts of food through the Digestive tract.…
Digestion is important for breaking down food into nutrients which the body uses for energy, growth and cell repair. When I am chowing down my steak and potatoes, my digestive system is doing that exact thing. Our digestive system breaks down food into smaller molecules and into nutrients for the body. These nutrients include carbohydrates, protein, fat and vitamins.…
Food begins its journey through the digestive system in the mouth, also known as the oral cavity. Inside the mouth are many accessory organs that aid in the digestion of food—the tongue, teeth, and salivary glands. Teeth chop food into small pieces, which are moistened by saliva before the tongue and other muscles push the food into the pharynx.…
This process of altering the chemical and physical composition of food so that it can be absorbed and used by body cells is known as digestion, and it is the function of the digestive system…
