8 Name: (first) (last) Day: Slot: The Human Digestive System Use pages in your textbook to find the following information. 1. (359) The process of digestion taken in by an organism into. 2. There are two main steps in this process. They are: a. MECHANICAL DIGESTION, which is. This occurs, where and. b. CHEMICAL DIGESTION, which is the. This process also begins in, with the. Then it continues in the and is completed in the. 3. On average, it takes hours for each meal you eat to complete its entire passage through your. Parts of the Human Digestive Tract 4. MOUTH (359) Upon entering the mouth, food comes into contact with, which is secreted by three pairs of. The saliva assists in the process of digestion (it starts digestion of C ). 5. The saliva also or food, so it will. 6. (Thinking questions) The mouth also contains teeth, the function of which is to and start the process of M D. The tongue, made of m, has the job of. 7. ESOPHAGUS (360) After leaving the mouth, food passes into a called the Esophagus. When you swallow, the food goes down the Esophagus. Swallowing also causes the E to close off the G (the opening to the T ), so that you don t choke. 8. The Esophagus is lined with along its length (about cm). The function of these muscles is to.
9 The Movement Of Food (see page 362) PERISTALSIS How does the food actually move through the digestive tract? The passage of food is helped by the physical effect of, which acts as a. Movement of food is accomplished by PERISTALSIS: a series of. Similar to what you would see if watching a eat a, alternating contracting and relaxing muscles along the digestive tract help to push food bit by bit along the tract. 9. STOMACH (360) After passing through the, the food then enters the : a m, -shaped, -like organ whose inside lining has millions of. These glands that is so important in CHYME(pronounced Kime ) is (see 765): -- mostly the digestion of P (the stomach is the first place that proteins are digested in the tract.) 10. Muscles lining the stomach work to and, making it into a called chyme (see box at right). 11. (See Stomach diagram at left) The stomach has two SPHINCTER MUSCLES: one at the top, where the food enters the stomach coming from the E, and one at the bottom, where the food leaves the stomach to enter the D.
10 The STOMACH LINING and ULCERS The inner wall of the stomach is lined with epithelial cells that secrete MUCOUS a sticky substance that protects the stomach lining. Cells of the wall also secrete HCl (Hydrochloric Acid) and Pepsinogen. The function of the HCl is to activate the pepsinogen to become a proteindigesting enzyme, PEPSIN. The enzyme Pepsin and the acid HCl could both eat away at the stomach lining but it is protected by the mucus. If for some reason the mucus lining of the stomach is not doing its job, or is lacking, the acid and enzymes could eat away at the stomach lining, resulting in an ULCER a sore that erodes the stomach wall away. (It can also be caused by bacteria.) 12. SMALL INTESTINE (361) After food leaves the stomach, it enters the D, which is the first part of the small intestine. The p duct and the b duct both open into the duodenum, making it an important site for. 13. The duodenum and the rest of the small intestine have, in their. These folds. This larger surface area the amount of that can be. 14. Along the folds of the duodenum and the small intestine are tiny, visible, finger-like projections called. The VILLI have a fine brush-like border of MICROVILLI. Together they serve to further increase the surface of the. 15. A capillary network (tiny blood vessels) is found inside the villi. They carry the nutrients to the bloodstream. There are also lymph vessels in the villi these accept and carry the larger that are.
11 16. LARGE INTESTINE (362) The large intestine consists of the c (where the small intestine meets the large intestine), the c, the r, and the a canal. The large intestine is long much than the small intestine. The APPENDIX (which plays in digestion, but might play some role in ) hangs suspended from the beginning of the large intestine. 16. In the COLON (the main portion of the ), and are absorbed from the, while help to break it down further to. (These bacteria also produce some v and some a a.) 17. The damp mass of that remains at the end of this process is called. It passes into the and, and then out through the (which has rings of called ). These sphincters allow the body to control the of elimination (egestion) to some extent.

13 Name (first) (last) Slot Date Other organs involved in Digestion Liver Pancreas Gall Bladder Produces BILE SALTS (see gall bladder) Breaks down old red blood cells, recycling them to make bile salts Stores excess chemicals in body Converts monosaccharides into glycogen, storing it until needed by the body (to adjust sugar levels) Stores some vitamins Detoxifies ingested poisons Source of several enzymes These enzymes work on fats, carbs, nucleic acids, and proteins Produces and releases a basic (i.e. not acidic) solution called bicarbonate into the duodenum (which changes the ph of chyme from a strong acid to a weak base). Produces and releases hormones glucagon and insulin, which regulate the body s sugar levels (also regulate fat and protein storage) Found on the underside of the liver Stores bile (from the liver) Releases bile to the duodenum when needed (via the Bile Duct) Bile acts to elmusify fats doesn t exactly digest them, but chops them into many smaller parts so they are more easily digested by lipases.
