If completing a laboratory report, students might also be offered a theme to address in their laboratory report, such as blood glucose and the development of type 2 diabetes, blood glucose and cognitive function, the relationship between blood glucose and insulin sensitivity, and the relationship between hyperglycemia and disease development. 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. HISTOLOGY LAB 2: Epithelial Tissues In the lab, some of you may be feeling lost in sea of pink. Students are also instructed to monitor others in their laboratory group. Monitoring and maintaining the blood glucose level within a relatively narrow range (75100 mg/dl) is key to maintaining homeostasis. 51 Breathing and Respiratory Volumes 52 Spirometry: BIOPAC Exercise. Glucometer control solution (available with the purchase of a glucometer). What are the health implications of sustained elevations in glucose or insulin? This laboratory provides an impactful and personal student experience highlighting key physiological concepts related to digestive and regulatory function. Between 60 and 120 min, blood glucose levels declined for all groups, with the HGL and OGTT groups demonstrating nearly identical levels at 120 min (111 4.7 in the HGL group vs. 111 7.4 in the OGTT group). Treatment nutritional information. 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. Bleach (diluted 1:10). 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. No differences existed between fasting levels, and therefore fasting levels are not reported. Myocardium.

In the Nervous System Views section, select . Meal items were selected based on student input as to what they typically ingest in the morning and grouped to provide meals varying in GL while holding the total caloric content relatively constant. Table 2. Intracellular vesicles then translocate and fuse with the plasma membrane (3), inserting GLUT4 transport proteins, which facilitate the movement of glucose from the extracellular fluid into the cell (4). The Anatomy & Physiology Laboratory Manual has been developed by Anatomy & Physiology Professors who have combined total of over 100 years of experience teaching A&P. Such atoms are useful for experiments that probe the transition from quantum-mechanical behavior to classical. Digestive physiology laboratory exercises often explore the regulation of enzyme action rather than systems physiology. What effect does insulin have in skeletal, adipose and liver tissue? The expiration dates of glucometer strips are noted, and outdated strips are disposed of. Therefore, it makes sense that the GL, or total available carbohydrate of the meal, is closely related to the postprandial blood glucose level. Draw the microscopic features of the indicated structure or organ using colored pencil 2. 14. Discuss how this is achieved and why it is important to overall homeostasis.
