In a humans mouth there are teeth and within a human they are four types of teeth which are used for different functions such as the incisor teeth are for biting and are found are the front of the mouth. The other types of teeth are the canines which are used for tearing food and premolars and molars which are used for grinding, pounding and crushing the food. The food that is taken in through the mouth is moistened by saliva which is a sticky fluid that binds the food particles together to create a soft mass. Saliva contains enzymes which are called amylase which digest the starch molecules into smaller molecules. When chewing food the tongue is used to move food about and manipulates it into a mass called bolus.
The Process of a Hamburger in Digestion A hamburger made of a beef patty, mayonnaise, and mustard on a bun. The bread is mainly made starch a carbohydrate, the meat contains protein and the mayonnaise and mustard are lipids. To begin with, digestion of the hamburger starts in the mouth. Here, mastication begins the process of mechanical digestion, in which the hamburger is broken down into smaller pieces by the grinding of the teeth and movement of the tongue. 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 tongue and teeth move the food around, mixing it with the saliva, with all 32 teeth tearing and crushing it to break it down further into a softer composition called a bolus. During the swallowing process, the epiglottis blocks the air passage to prevent food from going into the lungs. Once swallowed, the esophagus movies it by way of peristalsis, or squeezing and relaxing of the muscles, down into the stomach. The stomach acts as a holding tank for the food while it mixes further with gastric juices such as enzymes and acids from its lining, to break down the bolus into a thick creamy substance called chyme. After turning into chyme, it is sufficiently processed enough to release into the small intestine.
Mouth The mouth is the beginning of the digestive tract, digestion starts here when taking the first bite of food. Chewing breaks down the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Esophagus The esophagus is located in your throat near your windpipe; it receives food from your mouth when you swallow. The esophagus then delivers the food down to your stomach. Stomach The stomach holds food while it is being mixed with enzymes that continue the process of breaking down food.
SCI/241 THE SCIENCE OF NUTRITION January13,2012 Human Digestion How the does the digestive system works to absorbs nutrients? Digestion starts with the smell of food, it activates the salivary glands. The gland secret saliva that moistens food, it also contains a digestive enzyme called amylase that breaks down some carbohydrates before it leaves the mouth. Then the food is swallowed and goes into the lumen through the esophagus. The esophagus muscles contractions called peristalsis forces the food through the sphincter valve and into the stomach.
Name the organ systems involved when you eat a slice of pizza. - Digestive System includes mouth, salivary glands, esophagus, stomach, small intestine, liver, pancreas, gallbladder, and large intestine. 4.) You hear the expression “I sprained a ligament” or “I pulled my tendon.” Describe the type of tissue involved with each injury. Describe the function of a ligament and of a tendon.
_____ Trypsin digests complex carbohydrates to simple carbohydrates. 42. _____ Glycogen and starch are polysaccharides of glucose and both are stored in liver and muscle. 43. _____ The pancreas produces both insulin and glucagon.
Add 2 bottles of Newman’s Own Light Lime Vinagrette and Boil-in-bag Cajun seasoning. Put in onions, eggs(if desired) and garlic. Let ingredients come to a rolling boil and then add the sausage. After 10 min, add the potatoes. Let 10 more minutes pass then add the corn-on-the-cob.
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.
Describe the path food follows as it travels through the digestive system. Summarize the major structures and functions of those structures along the way. Any time you take a bite of food it begins its journey through the body, specifically the gastrointestinal tract, and it is fully digested and ready for elimination. If you were to begin with a piece of pizza, the moment you smell your wonderful slice of cheese pizza it begins to stir gastric juices in your stomach. Your stomach may “growl” alerting you that it is hungry and ready to be fed.
