How does the blood glucose level after the OGTT treatment compare with HGL, MGL, and LGL treatments? Sugar-free drink flavoring (used to flavor the oral glucose solutions). When purchasing food items, be sure to keep in mind that there are four treatment groups, with students divided among the groups. GI tract is a continuous tube extending through the ventral cavity from the mouth to the anus -it consists of the mouth , oral cavity , oropharynx , esophagus , Slides or pictures of these cell types might help. Although students are only asked to statistically compare the means of their treatment group to the means of the OGTT group, there were significant differences between meal treatments at various time points (Table 5). It may be worthwhile to have students complete research and determine the recommended number of calories necessary to maintain their weight given their sex, age, and activity level. These students may be asked to eat a normal meal, on a normal schedule, and test their blood glucose levels in the laboratory as a means of monitoring control of blood glucose. LABORATORY EXERCISE 47 DIGESTIVE ORGANS Figure Labels FIG. START by studying the relevant exercises, labeled models and slides.

Fig. Learners will be able to discuss concepts related to anatomy and physiology which can be applied to disease states. Anatomy and Physiology. 53 Control of Breathing. The study of relationships between various body parts, as well as their structure, is called anatomy, while physiology describes multiple functions of body parts and the body as a whole. Anatomy of the Digestive System. Take one or more of the tours (select bottom right) to It begins with ingestion and ends with defecation. The total GL of the meal is the sum of GLs of each food item in the meal. The following steps are performed on the day of the laboratory: 1. Through review of the literature, students will discover that variances can be attributed to many factors, including the size of the meal compared with the total energy needs of the individual, the type of diet a student normally consumes, and individual differences in insulin production and sensitivity. 3. 42 Digestive Physiology . The following materials are provided centrally at each bench and shared: Accu-check Compact Plus Glucometer with lancing device, lancets, glucometer test strips, alcohol wipes, hand sanitizer, sharps bucket, bench paper, biohazard disposal bags, 10% bleach solution for cleaning up, and graph paper.

Each student covers an area of the bench top with bench paper and designates this area as their personal area for blood testing. Make sure that test strips match the type of glucometer purchased and are not past the expiration date. Although the evaluation of A1C is a better indicator of glycemic control (and currently the recommended instrument for the diagnosis of diabetes), simple evaluation of fasting and 2-h plasma glucose remain valid as well (Table 4) (1). The authors approach to each exercise is to provide obtainable objectives followed by equally precise procedures with all needed materials listed for the students.

The GL of a particular food is the product of the glycemic index of the food and the amount of available carbohydrate in a serving. LAB EXERCISE 47 Urinary Structures 11 12 -4 A nephron, the basic functional unit of the kidney. However, the variability in the glycemic response does offer an opportunity to discuss insulin sensitivity and an array of factors (weight gain, physical inactivity, stress, birth weight, and genetics) that contribute to the development of insulin resistance. This results in increased production of ATP within the -cell. Proper procedures for safe handling of food are followed as food items are transported, stored, divided, and delivered to students (39b). an experiment, or a conclusion: 40 .

To get students to think through the implications of a diet consistently low in carbohydrate and high in fat, the instructor may pose the following question: Are there disadvantages to regularly consuming meals high in fat and low in carbohydrate? Find the wavelength of a photon resonant with the transition between these two states. The illustrated, print manual contains 55 A&P exercises to be completed in the lab, with guidance including instructions, safety tips, and tear-out worksheets. Views. Parotid duct 2.)

Even with a modified fast, all students report to laboratory with normal fasting blood glucose levels. Is there a link between glycemia, insulinemia, and the development of disease(s)? This will be used to clean bench tops before and after completion of this laboratory. Drinks often considered by students as healthier choices than soda also deliver significant amounts of sugar (20-oz Vitamin water: 33 g sugar, 20-oz Minute Maid lemonade: 67 g sugar, and 16-oz apple juice: 52 g sugar). edited and revised manuscript; M.K.H. The caloric value of the meals is 540 kcal. When blood sugar levels are high, glucose transporters (GLUTs) move increasing amounts of glucose into the -cells of the pancreas. Digestive physiology laboratory exercises often explore the regulation of enzyme action rather than systems physiology. 4 Pig Circulatory System .

Students will discover that many factors influence the glycemic response to a meal. Upon evaluation of the nutrient composition of the meals (Table 1), students realize that these meals ingested vary greatly in total carbohydrate, fat, protein, and fiber content. The following molecules or ions all have three oxygen atoms attached to a central atom. 39 terms. Occasionally, a student experiences an elevation in postprandial glucose above acceptable levels. Although MGL values were lower than OGTT values at 30, 60 and 120 min, this difference was statistically significant only at 60 min. The lymphatic system 1: structure, function and oedema. These subjects expressed appreciation for this laboratory as they learned of an existing condition that would have otherwise gone undiagnosed.

When presented graphs tracking postprandial blood glucose levels, students successfully interpreted the graphs and identified abnormal values as well as predicted the meals most likely to be associated with the resulting blood glucose levels. 41 Anatomy of the Digestive System . Palatine tonsils. Students are typically either junior or senior biology majors ranging in age from 20 to 25 yr old. Submandibular gland 3. 5. Digestion takes place in the gastrointestinal tract in two principal forms: mechanical and chemical. Therefore, it makes sense that the GL, or total available carbohydrate of the meal, is closely related to the postprandial blood glucose level. Ascending colon 8.) Anal canal Fill-in 1.) Digestive System. Bleach (diluted 1:10). Composed of cardiac muscle tissue. Digestive physiology laboratory exercises often explore the regulation of enzyme action rather than systems physiology. What structure penetrates the bone and holds the tooth firmly in place? Between sampling, the instructor reviews the digestion and absorption of macronutrients (carbohydrates, proteins, and lipids) and asks students to hypothesize as to the effect of their meal on postprandial blood glucose levels.
