A turkey and cheese sandwich would be divided into three categories: protein, carbs, and fat. The bread would be carbs, the turkey protein, and the cheese fat. This is how the process would go for each nutrient: Carbohydrates The digestion of carbohydrates starts in your mouth. Saliva contains the enzyme amylase. Amylase breaks down amylase and amylopectin (which are starches found commonly in foods such as pasta) and converts some of the starch maltose (a disaccharide.)
During this process, an enzyme in the saliva secreted by the salivary glands called amylase begins the breakdown of carbohydrates including starch in the bread into simple sugars. The glands secrete mucus, which moistens the hamburger making it easier to chew and swallow. Once the hamburger has been reduced forming a soft mass into a ball called a bolus. The tongue then pushes it to the back of the mouth and into the pharynx. The epiglottis then prevents choking by directing the bolus into the esophagus.
The digestive system is where food is turned into energy for the body to survive and it packages the residue for the waste disposal. When you first take a bite of the ham sandwich it is taken into the mouth, this process is called ingestion, where it is mixed with saliva then chewed or masticated by the teeth and tongue that roll it into a bolus and this motion is also known as mechanical digestion. The saliva that the sandwich is mixed with initially contains an enzyme called salivary amylase that starts the breakdown of carbohydrates so that your body can absorb them which is known as absorption. The food then passes own the oesophagus to the stomach. The oesophagus is a tube of muscles that contract to push the bolus down towards the stomach and this action is called peristalsis.
Stomach The stomach holds food while it is being mixed with enzymes that continue the process of breaking down food. Cells in the lining of the stomach secrete a strong acid and powerful enzyme that are responsible for the breakdown process. When the contents of the stomach are successfully processed, they are released into the small intestine. Small intestine The small intestine has 3 parts; the duodenum, jejunum, and ileum — the small intestine breaks down food using enzymes released by the pancreas and bile from the liver. It moves food through and mixing it with digestive secretions from the pancreas and liver.
As the teeth do their work, saliva mixes with the pieces of me, making me soft and moist. The saliva contains a chemical called salivary amylase, which starts breaking down complex carbohydrates, and another called mucin, which helps to soften the food. The amylase enzymes turn the starch molecules found in me into glucose. The glucose is used by cells to give people energy. oklahoma4h (2015) ptonthenet (2015) bbc.co.uk (2015) The tongue which is a muscle, works with me and saliva by pushing me around the mouth while you chew with your teeth.
From there the food moves to the small intestine. The small intestine is a long tube loosely coiled in the stomach. The small intestine continues the process of breaking down food by using enzymes released by the pancreas and bile from the liver. Bile is a compound that aids in the digestion of fat and eliminates waste products from the blood. Peristalsis
How is energy supplied in the Human Body? The human body is supplied with energy from the calories present in food. One gram of carbohydrates contains four calories; one gram of protein contains four calories while one gram of fat contains nine calories. Calories facilitate all body functions such as movement, breathing and playing. The digestive system helps break down this food into small pieces, the enzymes within the digestive system breaks the protein into amino acids, fatty acids and carbohydrates into glucose.
Support the absorption of carbohydrates and proteins B. accept chyme from the stomach and complete digestion C. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins 14. Slow the passage of food along the intestines and increase surface for absorption 15. A. Absorbs B12,bile salts, fluids and electrolytes and secretes enzyemes that further break down carbohydrates and proteins B. Creates a space for liquids to empty into C. Move waste up and out of the body D. Absorbs water from stool E. Absorbs water from stool and stores food that will be emptied into the rectumlts F. Moves stool into rectum 16. Secretes pancreatic juice, insulin, glucagon, duodenum, and somatostatin into the bloodstream.
Reticulum: in here, food and cellulose is digested by microbes ------ microbes are bacteria/ single celled eukaryotes ------ cows don't have enzymes to break down cellulose, so microbes do it for them ------ huge amounts of saliva create a good environment to help microbes digest the food ------ the food then goes back up to the esophagus to be chewed again and to make nutrients available for both cows and microbes --3. Omasum: water re absorption ------ Regurgitated food comes back as "cud" into reticulum and then to the Omasum --4. Abomasums: acidic environment where whatever is remaining is digested. excess microorganisms are harvested and digested. - NUTRIENTS (that they get): -- Sugars and proteins from grass are directly absorbed -- absorbing microbial digested grass molecules (cellulose --> glucose) --actual microorganisms themselves (they leak out sugars, fatty acids, etc.
Put down the slice of bread with the jelly on it back on the plate, next to the other slice of bread, with the jelly side up. The very last step is putting the sandwich
