The three nutrients found in the burger are proteins, carbohydrates, and fats. The protein comes from the patty, the carbohydrates come from the whole grain bun, and the fat comes from the mayonnaise. These nutrients are essential to the human body because each of them contribute to a certain part of the body. The digestion of protein starts in the stomach. The enzyme pepsin from the stomach starts to act on the protein molecules and breaks down the bonds into peptide bonds. It also splits the the longer protein chains into shorter polypeptides which are the chains of amino acids linked together. Those shorter polypeptides then pass through the pancreas which then head to the small intestine. The digestive enzymes trypsin, chymotrypsin, …show more content…
It begins in the mouth by the salivary glands from the enzyme that is called amylase. The salivary amylase breaks down the complex chains of polysaccharides into disaccharides molecules into maltose. The maltose is then broken into single molecules of glucose to provide energy. The disaccharides cannot be broken down by the salivary amylase so it moves to the stomach. Nothing happens in the stomach except that the digestive juices stop the action of the salivary amylase which then the disaccharides move down to the small intestine. The pancreatic amylase which is the enzyme released by the pancreas helps break down the disaccharides. The other digestive enzymes attached to the small intestine help split the disaccharides into two monosaccharide molecules. The maltose is split into two glucose units and the sucrose breaks down into one glucose and one fructose. The carbohydrates are chemically broken down into single sugar units and are transported into the inside of intestinal cells. The monosaccharides are absorbed by the small intestine and then enter the …show more content…
Digestion of fats begins in the mouth by the enzyme lipase. The lipase helps make the food easier to swallow. It helps break down the fat globules into much smaller emulsion droplets. The emulsion droplets are where the digestion of fat occurs. They help work to digest the triacylglycerol and so does colipase. This protein helps bind and anchor the pancreatic lipase at the surface of the emulsion droplet. The digestion becomes into the monoglycerides and fatty acids. These help form the micelles which transport the poorly soluble monoglycerides and fatty acids to the surface of the enterocyte where they are
in the stomach, and subsequently, the food is passed along to the intestine for more digestion and absorption
The digestive process begins in the mouth, known as the oral cavity, where food enters. Chewing breaks the food into pieces that are more easily swallowed, while saliva mixes with food to dissolve food molecules. After that the tongue pushes food toward esophagus. The esophagus is a muscular tube extending from the pharynx to the stomach. By means of a series of contractions, called peristalsis, the esophagus delivers food to the stomach. The stomach secretes acid by tiny glands. At the same time that protein is being digested with the enzyme pepsin to break down protein into smaller molecules. Beside these muscles of the stomach contracts rhythmically to squeeze food. All the directions the food becomes thick liquid like milk shake. Then the food arrives in the small intestine from the stomach through the opening of the pyloric sphincter. The pyloric sphincter muscle is the furthest part of the stomach that connects to the small intestine. The food fully digest and absorp nutrients in small intestine with the aid of liver, gall bladder, pancreas. So the digestive system is very necessary for
Emulsification or lipids- bile causes fat globules to break down or emulsify into minute droplets which increases the surface area of the fat making it digestible by lipase’s which cannot access the inside of lipid droplets.

4)Stomach: The stomach squeezes and mixes food with enzymes for hours before it releases the mixture into the small intestine.
Our chicken sandwich has, by now, been broken down into digestible nutrients. The pancreatic juices have broken down the carbohydrates in the bread into monosaccharides (such as glucose and galactose) which leave the enterocyte by facilitated diffusion and enter the rich network of capillaries. They are transported in the blood stream and cross into the cytoplasm by Na+ cotransporters. Amino acids are moved to the circulation by facilitated diffusion. Lipids from the butter are broken down into fatty acids by lipases and are then absorbed across the cell membrane into the cytosol where they are reassembled into lipoprotein particles called chylomicrons. These are carried through lymphatic channels and into the circulation via the thoracic duct. The bloodstream carries simple sugars, glycerol, amino acids, and a number of salts and vitamins to the liver. The lymphatic system, a network of vessels that carry white blood cells and lymph fluid throughout the body, absorbs fatty acids and
By observing the above operations process it is clear that the process is in control whereby the UCL, LCL and Sample range remain within a close proximity. This allows for the prediction of movement trends which helps improve future prediction and movement.
Mouth- Digestion begins in the mouth. Physical actions, such as chewing, breaks food into small parts so it can be easily digested. Next, salivary glands secrete an enzyme called saliva to mix with food to start the breaking down of carbohydrates (WebMD (2).) From the mouth, food travels to the pharynx, or throat, by swallowing,
...ve eaten, to break down the food into a liquid mixture and to slowly empty that liquid mixture into the small intestine. Once the bolus has entered your stomach it begins to be broken down with the help of the strong muscles and gastric juices which are located in the walls of your stomach. The gastric juices are made up of hydrochloric acid, water, and mucus- and the main enzyme inside of your stomach is what is known as pepsin, which needs to be surrounded in an acidic setting in order to do its job, that is to break down protein. Once the bolus has been inside of your stomach for long enough it begins to form into a liquid called chyme, and what keeps the chyme from flowing back into our esophagus are ring shaped muscles known as sphincters located at the beginnings and ends of the stomach and they have the task of controlling the flow of solids and liquids.
Imagine you are eating a sandwich containing wheat bread, ham, lettuce, and Swiss cheese. Do you ever wonder where the nutrients go from all of the previous listed ingredients? Well, when a bite of this sandwich is taken, the mouth produces a saliva enzyme called amylase. This enzyme immediately goes to work by breaking down the carbohydrates that are in the bread. Once, the bite is completely chewed, the contents then are swallowed and go down the esophagus and begin to head towards the upper esophageal sphincter and the is involuntarily pushed towards the stomach. The next passage for the sandwich is to go through the lower esophageal sphincter; which transports the sandwich into the stomach.
The function of the digestive system in the human body is to break down macromolecules into their individual monomers so the body can process them. There are two major types of digestion that occur in the body. These are mechanical digestion and chemical digestion. Mechanical digestion is the mechanical process of breaking down food particles into smaller pieces. Chemical digestion is the secretion of enzymes and chemicals that break down the food even further into their individual molecules. Some common enzymes in the human body are amylase, pepsin and lipase. Enzymes are catalysts that speed up reactions but aren’t reactants themselves. Different enzymes also react on different substrates, for example, amylase reacts on carboh...
During digestion, the body breaks down food into smaller molecules that could then be used by the body’s cells and tissues in order to perform functions. This starts off in the mouth with the physical movements of chewing and the chemical breakdown by saliva. Enzymes in the stomach break food down further after traveling from the mouth through the esophagus. The food from here then moves into the small intestine, where pancreatic juices and enzymes dissolve proteins, carbohydrates, and fibers, and bile from the liver breaks down fats into these small molecules. Any portion of the fibers or food that were unable to be broken down are passed from the small intestine to the large intestine, which is where the digestive tract transitions into the excretory tract, then the colon and out of the rectum. Any liquids that have been stripped of their nutrients by the body proceed from the stomach to the kidneys. In the kidneys, sodium ions (Na+), uric acid, and urea are exchanged with water, which moves urinary bladder and is excreted through the
Crunch, Crunch, Crunch. As you munch on those first few Cheetos the digestion process begins in your mouth. Here, mechanical digestion begins to reduce the size of the Cheeto and mixes the food particles with saliva. The tongue helps mix and move the pieces of Cheeto throughout the mouth. The salivary glands in the mouth also contribute to the breakdown of the Cheetos in the mouth. They secrete amylase and mucus. The parotid glands begin chemical digestion on the Cheetos. It secretes a clear, watery fluid that is high in amylase. The enzyme, amylase, begins to breakdown carbohydrates into disaccharides. The other two salivary glands, the submandibular and the sublingual, secrete saliva containing mucus, which binds and lubricates the Cheeto particles for easy swallowing. Now the food has been formed into a bolus with the help of saliva, the tongue, and teeth. Next the bolus travels into the pharynx, where the epiglottis closes off the top of the trachea so no food can enter. Then it moves on to the esophagus, where peristaltic waves push the food toward the stomach. The food enters the stomach through the cardiac sphincter at the end of the esophagus.
...he Buttermilk White bread. The food makes its way to the transverse colon and extra nutrients are released form the cellulose of the undigested particles. It continues on to the descending colon. There I start to manufacture vitamin K and other B-complex vitamins. Those are then absorbed into my large intestine.
The exocrine function of the pancreas is that it produces enzymes that aids in the digestion of food. There are three important enzymes that are crucial in helping with digestion. The first digestive enzyme is amylase. Amylase function is to break down carbohydrates. The amylase enzyme is made in two places: the cells in the digestive tract that produces saliva and the main one specifically found in the pancreas that are called the pancreatic amylase (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). The amylase in the pancreas passes through the pancreatic duct to the small intestines. This amylase in the pancreas completes the process of digestion of carbohydrates. Consequently, this leads to the production of glucose that gets absorbed into the bloodstream and gets carried throughout the body. The next enzyme that aids in digestion of food is protease. While amylase breaks down carbohydrates, protease breaks down protein. Protease breaks down protein into the building block form of amino acids. The three main proteases that it produces are: pepsin, trypsin and chymotrypsin (Marie, Joanne; Media Demand, “What Are the Functions of Amylase, Protease and Lipase Digestive Enzymes”). Pepsin does not occur in the pancreas but it is the catalysis in starting the digestion of proteins. Trypsin and chymotrypsin are the two proteases that occur in
