Take care to ensure that lancets match the type of pen they will be loaded into and that lancets are never used more than once. 2. Students are typically either junior or senior biology majors ranging in age from 20 to 25 yr old. A hydrogen atom is in the $n=45$ state. 33 Q Seperates nuclear contents from cytoplasm A . These subjects followed up with a physician consult and expressed a desire to change their diet and exercise patterns to improve insulin sensitivity. Duodenum 5.) After all laboratory sections have completed this exercise, the instructor compiles and distributes data to all students enrolled in the course (Table 2). There should be sufficient quantity to mix the required number of oral glucose solutions (75 g/person). At 60 min, blood glucose levels peaked for the OGTT group (151 8.4), whereas the HGL, MGL, and LGL groups showed a decline from 30-min levels. Food-grade dextrose (d-glucose) anhydrous (granular powder). Respiratory System. Therefore, the regulation of blood glucose, both fasted and fed, was ideal to meet our objective. 7. After the laboratory, students could be asked to conduct research and describe the characteristics of the meal as well as personal characteristics that influence their results. 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). Open the jaw wide enough so that the glottis and epiglottis are exposed. attaches the tooth to bone and surrounding alveolar structures, bisc 228 lab report 43 learn with When purchasing food items, be sure to keep in mind that there are four treatment groups, with students divided among the groups. An Accucheck glucometer is used to determine fasted and 30-, 60-, and 120-min postprandial blood glucose levels. 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. Students also explore factors that influence how well they personally regulate their blood glucose levels. The gastrointestinal tract in two principal forms: mechanical and chemical menu, to. Enamel 6.) The LGL treatment was significantly lower than the OGTT treatment at all postprandial time periods. Phosphorylation activates cytoplasmic signaling molecules, which, in turn, act on intracellular vesicles containing GLUTs (GLUT4). With its 46 lab exercises and hundreds of color photos and illustrations, the LABORATORY MANUAL FOR NON-MAJORS BIOLOGY, Sixth Edition, is your students' guide to a better understanding of biology. Anatomy of the Digestive System : Ex, 38, RS 593-598 . Although students are not required to determine statistically significant differences between meals, they do use paired t-tests to determine differences between time periods within treatment. You are responsible for all bold terms and answers. What are the current recommendations for percentages of carbohydrate, protein, and lipid in the diet? 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? \mathrm{SO}_3{ }^{2-} Universal precautions must be followed; all human blood must be treated as if known to be infectious for human immunodeficiency virus, hepatitis B virus, and other blood-borne pathogens. Anatomy & Physiology Laboratory Manual and eLabs, 11th Edition provides a clear, step-by-step guide to dissection, anatomy identification, and laboratory procedures. Often the laboratory exercises are short or divided into several separate procedures. Predict the postprandial blood glucose level based on the GL of a meal (process skill), 6. Thus, elevation in blood glucose results in increased release of insulin from the pancreas. Toaster pastries (any flavor, frosted, 2 toaster pastries/student).

START by studying the relevant exercises, labeled models and slides. Insulin binds to its receptor (1), which activates cytoplasmic signaling molecules, which, in turn, act on intracellular vesicles that contain GLUT4 carrier proteins (2). 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). prepared figures; M.K.H. 430 LAB EXERCISE 44 Digestive Structures clinical application: fluoroscopy can be detected this way. Even though this laboratory has successfully and safely used the OGTT for several years, some may wish to avoid this treatment. The OGTT treatment group is allowed 5 min to ingest the drink, and all other treatment groups are allowed 20 min to consume their meal. Wallpaper cosmic worksheet july 25, 2021. Between sampling, vibrant discussion covering such topics as glucose and cognitive function, insulin resistance, epigenetics, and fad diets occurs. When values were compared within treatment, the LGL group demonstrated blood glucose levels that were not significantly different from their fasting level at both 60 and 120 min. This highly modifiable laboratory exercise provides the opportunity for undergraduate students to write hypotheses, collect and analyze data, and draw conclusions from a data set that has visual clarity when graphed.

Give the name of each of the following simple binary ionic compounds.\ Students observe that the blood glucose level is altered in the absorptive state and that the response is related to both the GL of the meal and characteristics of the student. Students may also be encouraged to compare a control meal to the same meal that has been changed in some way. Respiratory System. Connect what you learn about anatomy and physiology to what you already know about your own body. Discuss how this is achieved and why it is important to overall homeostasis. The Cell: Transport Mechanisms and Cell Permeability . Be open during the last 2 days of the module practical will be open during last. Wall JS, Steele R, De Bodo RC, Altszuler N. Effect of insulin on utilization and production of circulating glucose. Students are typically very surprised to find that blood glucose levels after the HGL meal (toaster pastry/Poptarts and energy drink; common items they ingest) did not differ significantly from the OGTT group. The first of these processes, ingestion , refers to the entry of food into the alimentary canal through the mouth. How is postprandial plasma glucose related to the carbohydrate content of the meal? 2. No conflicts of interest, financial or otherwise, are declared by the author(s). The postlaboratory assignment requires students to discuss the importance of glucose homeostasis, graphically summarize their findings, review the literature to describe results in light of published data, and describe relationships between hyperglycemia and hyperinsulinemia and disease processes. 4 4.) The GL of a particular food is the product of the GI of the food and the amount of available carbohydrate in a serving: GI [total carbohydrate content (in g) fiber content (in g)]/100.

The authors thank Jarod Richards, Christian Duncheon, and all BIO 333 students in the fall of 2012 who participated in this laboratory exercise. Requiring students to write their hypotheses addresses the objective of having students predict postprandial blood glucose levels based on the GL of the meal. conception and design of research; M.K.H. 44 and 48 week) affects egg cholesterol in 40 week of production not 44 and 48. If inquiry based, it may be advisable for the instructor to provide access to published articles or other resources for students to determine the GI of individual foods (14) or the GL of the meal (6) and even consider the insulin response to the meal (5). Where does digestion begin? Identify each of the following as an observation, a hypothesis, As students conduct their research, they will learn that regular consumption of a very low carbohydrate diet is not feasible as carbohydrates are essential to maintain liver and muscle glycogen stores and ensure the delivery of glucose to tissues, such as those in the nervous system, that rely on glucose as their primary source of fuel. Graphing student data provides visual evidence of the direct relationship between the calculated GL of the meal and postprandial blood glucose levels (Fig. 3).

Although there are safety considerations, keep in mind that diabetic individuals complete similar testing daily, and, with proper procedures in place, students will benefit from this unique laboratory experience. Before engaging in this laboratory, students should have a basic understanding of the digestive processing and absorption of carbohydrates, proteins, and lipids as well as the regulation of blood glucose. Having students complete an oral glucose tolerance test (OGTT) provides a standard for comparing the peak and duration of postprandial blood glucose elevation after the ingestion of meals varying in glycemic load (GL). Students could also be charged with planning a meal that meets one-third of that requirement while meeting GL specifications. 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. Scribd is the world's largest social reading and publishing site. 2. 41 Organs of the Digestive System 42 Action of a Digestive Enzyme .
