Fantastic Voyage 2 Mary Burgess HS130-04 Unit #9 Assignment Kaplan University March 31, 2014

Good Evening everyone,

We are going on another Fantastic Voyage to the deep down under. My name is Mary Burgess and im gonna be piloting your minis sub. Our sub is only 8 microns long and can go through the hole body. This time we are gonna be swallowed by a 55 year old male named Billy. Billy will be eating a hamburger, French fries and drinking a coca –cola. Digestion begins in the mouth. A brain reflex triggers the flow of saliva when we see or even think of food. Saliva moistens the food while the teeth chew it up and make it easier to swallow. Amylase, which is the digestive enzyme, found in saliva, starts to break down starch into simpler sugars before the food even leave the mouth. The nervous pathway involved in salivary excretion requires stimulation of receptors in the mouth, sensory impulses to the brain stem and parasympathetic impulses to salivary glands. Swallowing his food happens when the muscles in his tongue and mouth move the food into his pharynx. The pharynx, which is the passage way for food and air, a small flap of skin called the epiglottis closes over the pharynx to prevent food from entering the trachea and causing choking. For swallowing to happen correctly a combination of 25 muscles must all work together at the same time. After being chewed and swallowed the food enters the esophagus or gullet is the muscular tube in vertebrates through which ingested food passes from the throat to the stomach. It connects the pharynx, which is the body cavity that is common to both the digestive and respiratory systems behind the mouth, with the stomach, where the second stage of digestion is initiated. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic wave like muscle movements called peristalsis to force food from the throat into the stomach. Once in the stomach the food then mixes with gastric acid. After being in the stomach, food enters the duodenum, { duodenum} - the first part of the small intestine; it is C-shaped and runs from the stomach to the jejunum. . It then enters jejenum, { jejunum} - the long, coiled mid-section of the small intestine; it is between the duodenum and the ileum. {Ileum}- the last part of the small intestine before the large intestine begins. In the small intestine, bile (produced in the liver and stored in the gall bladder), pancreatic enzymes, and other digestive enzymes produced by the inner wall of the small intestine help in the breakdown of food. Now after going thru all the swishing around and being mixed all together were headed into the large intestine. In the large intestine, some of the water and electrolytes (chemicals like sodium) are removed from the food. Many microbes (bacteria like Bacteroides, Lactobacillus acidophilus, Escherichia coli, and Klebsiella) in the large intestine help in the digestion process. The first part of the large intestine is called the cecum (the appendix is connected to the cecum). Food then travels upward in the ascending colon. The food travels across the abdomen in the transverse
