And band-aids ) to guard against exposure to blood from other individuals -cell. Ulcen, holes in the digestive wall, can. In response to these findings, it is appropriate to pose the following question to students: Why do these meals result in different glycemic responses? Adv Physiol Educ 33: 209212, 2009.

Pyloric canal near pyloric sphincter In addition to differences in digestive processing related to meal composition, the functioning of control systems influence the postprandial glycemic response. Helpful? Chronically elevated blood glucose (hyperglycemia) may also impair neuronal function and cause damage associated with the development of type II diabetes (9), cardiovascular disease (12), and even certain types of cancer (33). Tongue 5.) 11. Correctly use anatomical terminology to identify the organs and tissues involved with the overall digestion of materials being consumed Students could also be charged with planning a meal that meets one-third of that requirement while meeting GL specifications. Record pH of solutions in Table 4. The stomach produces a mixture of fluids called gastric juice in response to neural stimulation (induced by smell, site and taste of food), by distension of the stomach as food enters, and by pH changes induced as the more neutral pH food enters the acidic stomach. TEST COLOR INDICATOR: IKI: Purple=Starch, Red=Dextrin, Tan/Yellow=Maltose; Benedicts Solution: Orange/Yellow = disaccharide present (low, moderate, high), Green= trace amounts of disaccharide, Blue= no disaccharide (negative). For humans, digestive enzymes function the best at temperatures of 37oC and will be drastically impacted by temperatures above or below this temperature. 12.

From the general supply area obtain 8 clean test tubes, and pipettes Repeat the timer for 15-minutes examining the egg at 15-minute intervals for signs of digestion for a total of 1-hour. However, efficient fat digestion also involves the secretion of bile from the liver and gall bladder. What would you expect to happen if tissues (skeletal, adipose, and liver) became insulin resistant? Indeed, without the presence of these enzymes, chemical digestion would essentially not occur.

CliffsNotes study guides are written by real teachers and professors, so no matter what you're studying, CliffsNotes can ease your homework headaches and help you score high on exams. o Fundus 2. Pepsinogen can digest some ingested protein, but more importantly pepsinogen molecules will partially digest one another, removing inhibitory segments of the polypeptide chain and thus converting each other into the fully active enzyme pepsin. o Esophagus stomach Cap the test tubes and shake to mix for 30-seconds Digestive System. o Secretion Physician consult and expressed a desire to change their diet and exercise patterns to insulin. Digestion starts in mouth and it is going through several steps. Many of these substances facilitate the breakdown of food (i.e. Xuys pas through the patient and are alsorbed by the screen's enating. 4 ExErcisE MARI1702_11_C04_pp018-023.indd 18 2/20/13 10:10 AM Anatomy & Physiology I & II. Thus, for fat digestion to be efficient, the large droplets must be broken into much smaller droplets and held in these smaller droplets in order to increase surface area and enable enzymes (lipases) adequate contact with their substrate. S ) are performed on the blanks in t at the end the however, foods not. Although the chemical digestion of protein begins in the stomach through the actions of pepsin, most of the digestion of protein takes place in the small intestine. As a group, think about: Why do you need to test a control solution in the experiment? Digestion of food into small, absorbable molecules Lancets can also be purchased separately. o controls passage of food from the laryngopharynx esophagus Students also discover that the presence of fat and protein in the meal likely serves to moderate the postprandial response as fat delays gastric emptying and tends to flatten the postprandial plasma glucose response (10). Composed of cardiac muscle tissue.

Pyloric antrum next to body Pyloric Sphincter Explain why mechanical digestion only occurs in the mouth by teeth and muscle activity o Tube that extends from mouth to the anus 3. Many factors, including being overweight (21, 31), lack of physical activity (22), stress (39), birth weight (24), and family history (27), have all been linked with the development of insulin resistance, or the inability to respond properly to insulin. An example of this would-be pepsinogen that must be exposed to the acidic pH (2.0) within the gastric secretions to become active and digest proteins into short-polypeptide chains. The beaver pond analogy of blood glucose control. Students shared 8 documents in this course.

The pattern of teeth we have is considered to be and includes incisors, canines (cuspid), pre-molars (bicuspid) and molars. Transfer test tube into test tube rack in incubation temperature as indicated in Table 1B. Lancets and a lancet pen. A number of different proteases are found within pancreatic juice, but most are released as zymogens (inactive enzymes). o Generally the human stomach can hold up to about 1 L, but it can . Do not forget any table that may require definitions or identification functions of the different organ or system structures listed 5. Palatine tonsils. In this sample data set, fasting blood glucose levels are within the normal range of 75100 mg/dl for all students, and there are no significant differences in fasting glucose between treatments (Table 2 and Fig. Box 817 When drawing, begin to draw from the bottom and continue to draw in Pepsin as you slowly pull pipette from bottle. Chemical digestion of protein begins in the stomach. Mechanical digestion: mechanically breaking food into smaller pieces 41 Anatomy of the Digestive System .

Adopters of this activity are responsible for obtaining permission for human or animal research from their home institution. The anatomical structures of the Digestive System Table 3 greater omentum Cecum Small intestine Mesentery intestine! Most organs will function based solely on the ingestion of materials and are not regulated to alter the amount of any individual type of material that can be absorbed. Gastric juice contains a number of substances, but the two most important for initiating protein digestion are hydrochloric acid (HCl) and the protease pepsin. The end of mastication results in swallowing and the initiation of peristalsis, the coordinated contraction of muscles (circular and longitudinal smooth muscles) of the alimentary canal to propel food materials from the mouth to the anus in roughly 24-hours.
