Ingestion munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350787842 The place where all the magic begins is your mouth. The process of taking any substance in your mouth is called ingestion. As soon as you start chewing on my carb filled bun, my protein oozing meat, or that fat-filled cheese, that is all ingestion. Mechanical digestion which is the grinding and chewing of food or in other words me, is where it will all start. The mouth has many organs which aid in my breakdown and digestion such as your teeth which will start chopping me down into smaller pieces. Chemical digestion will now begin its process of food mixing with saliva. The tongue will moistened me up as the salivary glands excrete a watery substance called saliva along with salivary amylase which will help break down my carbs. The saliva is what helps make it easier for me, the burger, to pass through your esophagus. My chewed up pieces will then go through the pharynx which is the part of throat behind the nose which serves as a pathway so the food can be swallowed to the esophagus. The esophagus is where boluses of food from the throat are taken to the stomach. The chewed up pieces will go through the esophagus by wave-like muscle contractions called peristalsis. After the esophagus completes it tasks, the food will move on to the stomach where digestion will begin. ]]> 2019-04-11 14:22:16 UTC https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350787842 2. Digestion munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788113 Digestion is the process in which your food is broken down in order for nutrients to be absorbed. Mechanical and chemical digestion as explained in ingestion also occur in the stomach. In mechanical digestion the stomach will break down my large pieces into smaller pieces by churning me. Stomach glands will start to secrete different acids in order to break me up into smaller pieces. Hydrochloric acid or stomach acid, is what activates other enzymes to carry out certain tasks it can't directly do. This hydrochloric acid is activated by gastrin which is a hormone that stimulates gastric acid or HCI to be released. HCI activates an enzyme called pepsin but before pepsins can be activated, your stomach releases pepsinogens from eating protein. When pepsinogens are mixed with your stomach acid, it will activate an enzyme called pepsin. Pepsin is an enzyme which breaks down proteins into smaller peptides. These pepsins will take my sources of protein such as cheese or mayonnaise and break them down into amino acids your body can absorb. These acids will continue to chemically digest which turns into a mixture of food, stomach acid, saliva, and enzymes called chyme. All of this will be further chemically digested in absorption. ]]> 2019-04-11 14:22:44 UTC https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788113 3. Absorption munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788196 The small intestine is the beginning of absorption and this is where 90% of absorption and digestion takes place. The duodenum is the first part of the small intestine where all the chyme will be moved to. There are a couple of nutrients that come into play as soon as I enter the duodenum and those are secretin, cholecystokinin, and bicarbonate. Secretin helps regulate pH levels in order for other digestive enzymes such as trypsin to work. Cholecystokinin or CCK for short is a digestive hormone that comes along with secretin when released into the duodenum. It stimulates the gallbladder into releasing its stored bile into the intestine. Bicarbonate is another nutrient that acts as a pH regulator. It's released by the pancreas in response to secretin in order to neutralize the acidic chyme that came from the stomach. The pancreas is an organ which will secrete digestive enzymes to the duodenum. These enzymes include trypsin, pancreatic amylase, and lipase. Trypsin is an important enzyme for protein absorption as protein Is usually too big to be absorbed by the lining of the small intestine. Trypsinogen is the inactivate form of this enzyme secreted by the pancreas. In order for trypsin to become trypsinogen, the enzyme enterokinase will need to change trypsinogen into an activate protein. Pancreatic amylase is what will help complete the breakdown of my carbohydrates. Pancreatic lipase is an enzyme which will help complete the breakdown of my fats. All the chyme will then be mixed with bile. Bile salts are a primary component in making bile but bile itself is a fluid made by the liver and stored by the gallbladder which stores the bile made from the liver. When the bile is ready to be used, the gallbladder will release it into the duodenum to further help with absorption and digestion of fats. The liver has a few functions but its main ones are to make bile which is used by the small intestine and to process the nutrients absorbed by the small intestine. The jejunum is the next part of the small intestine. The jejunum is the middle part of the small intestine and is where all nutrients such as sugars, amino acids, and fatty acids once they've been broken up get absorbed and put into the bloodstream.The last part of the small intestine is the ileum. It contains vili and absorbs everything the jejunum failed to absorb and vitamin b12 along with bile salts. When my nutrients are ready to be absorbed, cells will allow my nutrients to flow into your blood to be absorbed. Once my nutrients have been absorbed, they will be carried away from the small intestine through the hepatic portal vein to the liver. The liver will remove all my toxins and process all my nutrients. After all this occurring in the small intestine, I am now ready to move on to the large intestine aka the colon. ]]> 2019-04-11 14:22:54 UTC https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788196 4. Egestion munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788276 Egestion is the discharging of undigested food material from the body. The large intestines have three parts which will help with this and they are the cecum, colon, and rectum. The cecum absorbs fluids and salts that can't be broken down anymore. The cecum mixes it's content with mucus. Mucus is a lubricant used to get materials down your body. The colon will now re-absorb my fluids and prepare for my waste to leave your body. The rectum is the second last part of large intestine. This is where all my undigested waste is being kept in your body until you can excrete it through your anus. The anus is where all the waste is finally let out from. That is how I live my day to day life. I hope you washed your hands after that bathroom trip!]]> 2019-04-11 14:23:06 UTC https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350788276 Introduction munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350791238 Hello there! My name is hamburger or you can call me hammy and this is a story about my typical days of going through the human digestive system. It doesn't sound that appealing but trust me when I say... it's actually quite interesting. Read on to found out how I go through your digestive system. ]]> 2019-04-11 14:27:22 UTC https://padlet.com/munabooxx/h7gv58vv8g0e/wish/350791238 References munabooxx https://padlet.com/munabooxx/h7gv58vv8g0e/wish/351194523 1.   Reagan, Owen. “The Digestive system mouth.” Innerorgans
