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. conception and design of research; M.K.H. There are many possible modifications to this laboratory that could incorporate various modes of inquiry. Anal canal Fill-in 1.) Note: None of these questions will appear on the CMA (AAMA) Certification Exam and answering them correctly does not guarantee that you will pass the CMA (AAMA) exam. 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. Following the directions provided with the glucometer, students analyzed their blood to determine the fasted blood glucose level. Completion of this laboratory as written requires 2.53 h. To shorten the time required, students could be asked to eat at a set time before class or assess postprandial sugars for a shorter time period. 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). Fig. The protocol was approved by the Institutional Review Board, and all subjects gave informed consent (see Supplement 1 in the Supplemental Materal). 2. Furthermore, these excited states have extremely long lifetimes (i.e., the electron will stay in this high excited state fora very long time). 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? 10. This laboratory exercise covers the following animals. No differences existed between fasting levels, and therefore fasting levels are not reported.

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). 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. 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. Values are from Ref. The following are articles from Advances in Physiology Education: 1. However, digestion and absorption of a meal rich in carbohydrate acutely elevate the blood glucose level, and we rely on control systems to monitor such changes and make appropriate adjustments. Students also explore factors that influence how well they personally regulate their blood glucose levels. The major salivary glands (parotid, submandibular, and sublingual) in the human and the cat occupy similar locations. 24 terms. Antiseptic hand cleanser and/or hand soap and paper towels.

Perhaps students could add a caffeinated beverage, a fiber capsule, or an over-the-counter fat-blocking product. Some of these structures are the pharynx, crop, gizzard, intestine, and accessory glands. Discussion is always vibrant, and students are encouraged to use both laboratory computers and personal devices to gather information pertinent to the conversation. 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. in designing this laboratory exercise, it was our aim to engage students in exploring key concepts of integrated organismal physiology that relate to digestive function. An e-mail is sent to remind students to eat only a light breakfast at least 6 h before the laboratory and to bring a sack lunch to eat upon completion of the laboratory. 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. Table 2. 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. Table 1.
