https://padlet.com/natalie_pilot13/qnn8wqdvc1mb A story simulation of food going through the digestive system. A few students travel through the system with pieces of food and encounter digestive organs and discover their role in digestion. en-us 2017-10-31 23:37:26 UTC 2023-11-19 12:39:41 UTC hello@padlet.com natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347699 Which means... now we excrete our waste and go to the bathroom. ]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347699 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347700 Finally we move into the large intestine. This is where the water is absorbed. At the end of the large intestine, is the anus. This is where all the waste is removed form our bodies. The large intestine is made up of the cecum. Stool, or waste left over from the digestive process, passes right through the colon by the means of peristalsis, first in a liquid state and ultimately in solid form. As stool passes through the colon, and any remaining water is absorbed.]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347700 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347701 Now class, we move into the small intestine. It is called the small intestine since it is very small in diameter. This is where all digestion starts to come to an end. Therefore starch, protein and fat digestion continue until all food is absorbed. The small intestine also breaks down food using enzymes released by the pancreas and bile from the liver. This is where most nutrients are absorbed. Peristalsis is also at work in this organ, moving food through and mixing it up with the digestive secretions from the pancreas and liver, including bile. The duodenum is largely responsible for the continuing breakdown process, with the jejunum and ileum being mainly responsible for absorption of nutrients into the bloodstream.]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347701 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347702 The SS Pilot moves onto the last of the three organs. This is called the pancreas. The pancreas makes digestive enzymes for proteins, lipids, and carbohydrates. These enzymes are very important because they allow your body to break down the food so it can be turned into something your body needs like energy. This is where something called Enterokinase takes place,  an enzyme secreted from the duodenal mucosa, that changes the inactive pancreatic secretion trypsinogen into trypsin, one of the enzymes that digest proteins.]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347702 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347703 This little green organ is called the gallbladder, which is underneath the liver. This organ stores the bile produced in the liver until it is needed for digesting fatty foods in the duodenum of the small intestine. Bile serves two main purposes. First, it helps absorb fats in the diet, and secondly, it carries waste from the liver that cannot go through the kidneys.]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347703 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347704 This is the liver. The liver processes the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting lipids. ]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347704 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347705 Next we go onto the stomach. Here, both physical and chemical digestion occurs. Physical digestion is occurring because of the churning of the stomach. Chemical digestion is also occurring because the stomach is very acidic. This causes starch digestion to continue and protein digestion begins here as well. This is very important cause protein is the building block of your bones, cartilage and muscles and of course skin. IF you notice the three other organs, these are known as the auxiliary organs since they aren't apart, but they aid digestion. The cells in the stomach secrete pepsin to help you digest the protein that you consume in food. ]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347705 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347706 Next the SS Pilot moves onto the esophagus. In this part of the digestive tract, no "digestion" takes place. It is basically just a long tube that goes form your mouth to your stomach through the sequential contraction of muscles known as peristalsis. ]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347706 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347707 Now we have entered the mouth. This is where physical and chemical digestion occur. Physical digestion with your teeth breaking it into smaller pieces and chemical digestion by using your saliva to chemically break down food. In the mouth we have the pharynx, and salivary glands which produces saliva. , the]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347707 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347708 We are off, the SS Pilot is off! We shrunk into the meat of the burger. Now we begin our journey through the digestive system and every part of what happens to food in our bodies. Information to remember as we go through, there are 6 steps in destroying your food and release and recycle nutrients. Ingestion, Propulsion, Mechanical breakdown, Chemical digestion, Absorption, and lastly Deification. ]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347708 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347709 Today the class is going to shrink and travel in a submarine through the digestive system. We are going to be following our food (the hamburger) through our body by the bread being a carbohydrate, the cheese being a fat, and the meat being a protein.]]> 2017-10-31 23:37:26 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202347709 natalie_pilot13 https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202367706 Now that our journey is done, this is the path we just went through in the mans body. We just went through our Alimentary canal aka Gasatroinrstnal tract. ]]> 2017-11-01 02:24:38 UTC https://padlet.com/natalie_pilot13/qnn8wqdvc1mb/wish/202367706
