I have meat, cheese and a noodles, which is protein, lipids and carbohydrates. In that exact order actually. Today, I am going to talk to you about something that I have been waiting to happen for what seems like my whole life, I am going to be digested. Sounds like an odd thing to be excited for but I have been looking forward to this all day! This process is divided into four stages or steps and I am going to be telling you about these as I am experiencing them. Ready? Let's go! becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203412646

The teeth quickly break up all my parts into smaller pieces, using the different types of teeth. The incisors and canines for grabbing and cutting and the molars and premolars for grinding and crushing. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203422642 2017-11-03 18:07:08 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203422642 Ingestion: the process of taking food into the body through the mouth becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203428256 2017-11-03 18:15:55 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203428256 The smell of me in the mouth initiated the salivary glands to secrete saliva. This saliva contains enzymes and one of those enzymes are called amylase and that breaks down starch that is present in my noodles. The saliva also dissolves my particles and actually allows the host to taste me and all my good spices and the different parts of me. But the saliva also contains mucus which is a protective secretion that is a lubricant which helps in swallowing. The tongue then pushes me into the pharynx. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203435872 2017-11-03 18:31:01 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203435872 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203444421 2017-11-03 18:51:33 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203444421 Digestion: the process of breaking down food by using enzymes, hormones and nerves. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203444696 2017-11-03 18:52:13 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203444696 As I travel down the pharynx, I get to the esophagus. The esophagus is a long muscular tube that carries me from the pharynx to the stomach. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203446822 2017-11-03 18:57:47 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203446822 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203463521 2017-11-03 19:54:46 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203463521 The next section is the stomach. It's a J-shaped organ that continues the digestion that was started at the beginning stage of ingestion. The stomach has four layers and the first layer one is called mucosa and this layer produces gastric juice. Gastric juice is a mixture of digestive enzymes, acid and mucus. The next layer that I enter is the sub mucosa which is a layer of connective tissues and it contains a network of nerves and blood vessels. The third layer is called the muscularis and it is a layer of smooth muscles; these muscles contract very often and they start churning and mixing me up, and I am currently mixed with gastric juice and I am a semi-liquid that is called chyme. The last layer of the stomach, the serosa, actually holds the stomach in place and produces lubricating fluids that ensures there is no friction between organs. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203463981 2017-11-03 19:56:54 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203463981 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203465166 2017-11-03 20:03:13 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203465166 An important thing that I should mention is that the gastric juice contains hydrochloric acid and this converts pepsinogen to an active form called pepsin and this begins the breakdown of my meat and separates amino acids. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203472053 2017-11-03 20:33:30 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203472053 The next section that I enter is the small intestine but specifically the duodenum which is the first section of the small intestine. A lot of enzymes are added here and then I move on to the next section which is the jejunum and some nutrients are absorbed here. It is hard to tell if I am still in the jejunum or the ileum which is the last part of the small intestine. In this section, a lot of my nutrients are absorbed. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203476396 2017-11-03 20:58:21 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203476396 Before I enter the first section of the small intestine, I go through the pancreas. This is long and flat and it seems to be secreting some sort of enzyme. It also secretes hormones called cholecystokinin (CCK) and this is released into the bloodstream. The pancreas also releases trypsinogen, which is an inactive from of trypsin and this travels from the pancreas to the duodenum and once it reaches there, an enzyme called enterokinase converts it into active trypsin. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203477351 2017-11-03 21:05:02 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203477351 The liver was the biggest organ that I have seen during this whole time. It produces bile and bile breaks up fat which is my cheese, into tiny droplets called micelles. The bile from the liver is stored in the gall bladder. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203480484 2017-11-03 21:25:02 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203480484 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203483988 2017-11-03 21:50:59 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203483988 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203484258 2017-11-03 21:53:39 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203484258 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203484807 2017-11-03 21:59:24 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203484807 The nutrients of my cheese, meat and pasta noodles have been absorbed in the jejunum and ileum. Vitamins, minerals and water are absorbed in the small intestine. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203485430 2017-11-03 22:07:08 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203485430 Absorption: the process of absorbing nutrients becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203485451 2017-11-03 22:07:24 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203485451 Egestion: the process of voiding or discharging undigested food as feces becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203485573 2017-11-03 22:09:21 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203485573 The next part that I went into was the large intestine. But specifically the colon which is the largest part of the large intestine and actually four parts: the ascending colon, the transverse colon, the descending colon and the sigmoid colon. I went through all four of these sections. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203485941 2017-11-03 22:14:16 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203485941 After going through the colon and what was left of me went to the rectum. This is where the waste products of digestion until I am eliminated through the external opening called the anus. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203488294 2017-11-03 22:49:20 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203488294 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203488951 2017-11-03 22:54:29 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203488951 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203489519 2017-11-03 23:04:43 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203489519 The absorption of water in the large intestine changes me form my liquid state to a soft solid that was now called feces. becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203489653 2017-11-03 23:06:13 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203489653 becka_18 https://padlet.com/becka_18/c79bbmiollil/wish/203490096 2017-11-03 23:13:03 UTC https://padlet.com/becka_18/c79bbmiollil/wish/203490096 1. “Anatomy of the Mouth.” WebMD, WebMD, www.webmd.com/oral-health/anatomy-of-the-mouth. 2. “Esophagus.” The Free Dictionary, Farlex, medical-dictionary.thefreedictionary.com/esophagus. 3.
