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). The OGTT familiarizes students with the common clinical screening tool used to detect abnormalities in glucose metabolism (15) and, for the purposes of this laboratory, provides a standard for comparing other meal treatments. Adv Physiol Educ 33: 209212, 2009. 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.

Energy drinks (small size, 8 oz, 1 energy drink/student). 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. Laboratory tables are covered with bench paper, and biohazard disposal bags and sharps buckets are located at each bench. Left and right hepatic 3.) Does proving this relationship really matter? Duodenum 5.) Food begins its journey through the digestive system in the mouth, before being pushed by a series of involuntary muscle contractions through the esophagus, then the stomach, and then the small and large intestines. Are these recommendations advised for everyone? All of the anatomy students attended two 50-min lectures together each week. 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). aglazebrook0001. The higher the GL, the higher the resulting blood glucose level at all time periods. 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? Blood glucose levels are recorded in the data table (Table 2).

Activity 1: Microscopic Observation of Digestive Structures Observations: Be sure to include written descriptions of the tissues and structures you observed in addition Disposable laboratory safety (exam) gloves. This approach has been more effective for systems such as the cardiovascular and respiratory systems, where measures such as heart rate, blood pressure, breathing frequency, and lung volumes can be obtained noninvasively. In the Nervous System Views section, select . Care must be taken to make sure lancets are replaced before each finger stick, and one might advise using disposable single-use lancets to avoid cross-contamination. Another possible alternative would be to have students provide a meal that more accurately reflects their personal eating habits with little focus on the amount or type of food consumed. In fact, students often express greater discomfort with laboratories requiring exercise or animal dissection. The major salivary glands (parotid, submandibular, and sublingual) in the human and the cat occupy similar locations. Table 2. How are carbohydrates digested and absorbed? Parotid glands.
