To predict: The response of pancreas when an individual eats a hot fudge sundae.
Introduction: The pancreas is an elongated organ located in the abdominal cavity behind the stomach. It is considered as the heterocrine gland, because it releases their secretions into the blood and digestive tract. The function of pancreas is to release insulin and glucagon into the blood, which is necessary to maintain the glucose concentration in the blood.
To determine: The antagonistic actions of insulin and glucagon in regulating the blood.

- A scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli. Which observation would support this hypothesis? Insulin is produced in response to sudden stress without a rise in blood glucose Insulin is produced in response to a rise in glucagon levels Beta cells express epinephrine receptors Insulin is produced in response to a rise in blood glucose in the brain.arrow_forwardVisit this link (http://openstaxcollege.org/l/pancreas1) to view an animation describing the location and function of the pancreas. What goes wrong in the function of insulin in type 2 diabetes?arrow_forwardFigure 37.11 Pancreatic tumors may cause excess secretion of glucagon. Type I diabetes results from the failure of the pancreas to produce insulin. Which of the following statement about these two conditions is true? A pancreatic tumor and type I diabetes will have the opposite effects on blood sugar levels. A pancreatic tumor and type I diabetes will both cause hyperglycemia. A pancreatic tumor and type I diabetes will both cause hypoglycemia. Both pancreatic tumors and type I diabetes result in the inability of cells to take up glucose.arrow_forward
- Describe the negative feedback control of blood glucose levels, and explain the roles of insulin and glucagon in regulating blood glucose levels. ANSWER SHOULD INCLUDE: Explain the meaning of "negative feedback control', Name the 2 hormones involved and which part of pancreas produces each one Explain the stimulus for release of each hormone. Explain the response to hyperglycaemia (what happens to glucose? Explain the meaning of term such as facilitated diffusion, glycogenesis , gluconeogenesis) Explain how blood glucose returns to normal (homeostasis) Explain the response to hyperglycaemia (what happens to glucose? What happens in glyconeogenesis?) In which organs do these events occur? Explain how blood glucose level returns to normal (homeostasis)arrow_forwardDiscuss and trace the pathway of the production of insulin, starting from the stimulation by glucose.arrow_forwardThe chemical bisphenol-A (BPA) is used to make plastic bottles and to line cans. Evidence from animal experiments and epidemiological studies indicates that the risk of obesity rises with increased BPA intake. How might the endocrine-disrupting effects of such a chemical influence body weight?arrow_forward
- Contrast the roles of insulin and glucagon in regulating blood glucose levels.arrow_forwardThe _ is the region that triggers hunger in response to signals from nerve cells and messages carried by hormones? A. Pancreas B. Hypothalamus C. Insulin D. Pituitary glandarrow_forwardDescribe how the pancreatic hormones interact to regulate blood glucose levels.arrow_forward
- What is the effect of aging on glucose regulation? Give specific rational A.Decreased response to insulin B.Increased secretion of glucagon C.Increased oxygen utilization D.Decreased platelet productionarrow_forwardIn order to help Mike understand, explain how the rate of insulin release differs after consumption of simple andcomplex carbohydrates. You may choose to answer with words or a labeled diagram Now use your table to explain to Mike why elevated insulin levels are associated with heart disease.arrow_forwardA scientist hypothesizes that the pancreas’s hormone production is controlled by neural stimuli.
