either noncompliant with insulin therapy‚ or have serious underlying illess that precipitates DKA. Most such patients have type I ("insulin dependent"‚ "juvenile onset") diabetes mellitus‚ but it has recently been increasingly recognised that patients with type II diabetes mellitus may present with ketoacidosis‚ and that some such patients present with "typical hyperosmolar nonketotic coma"‚ but on closer inspection have varying degrees of ketoacidosis. 2.

process of change. Explain the role of insulin and glucagons in regulating blood sugar. The human body requires that the blood glucose level is maintained in a very narrow range. Homeostasis is regulated by two hormones‚ insulin and glucagon which are both secreted by the endocrine pancreas. The production of insulin and glucagon by these pancreatic cells ultimately determines if a patient has diabetes or another related problem. Insulin is secreted by the beta cells of the

trigger to the alpha cells to secrete glucagon on liver cells (Tortora et al.‚ 2014 p644)‚ the glucagon works primarily on the liver cells which converts the stored glycogen into glucose and distribute into the blood and promote gluconeogenesis where there is a formation of new glucose from lactic acid and amino acids or other metabolites in the body (Tortora et al.‚ 2014 p644). As a result of the hormone from the alpha cells of the pancreas which is the glucagon it releases the glucose in to the blood

which releases the peptide hormones‚ insulin and glucagon‚ to regulate blood glucose levels. Insulin and glucagon are hormones and are dynamic chemical regulators. They both have a huge effect on metabolism despite the fact that they are produced in small quantities. These two are antagonistic hormones meaning an opposing (antagonistic) hormone often counteracts the effects of one hormone. Therefore‚ feedback mechanisms adjust the balance of insulin and glucagon so it may maintain a physiological function

Insulin is located in the pancreas and the action of insulin is remarkable and also not as complex as most people would think. Glucose is taken up by a muscle that is at rest‚ which in turn regulates blood glucose concentration. This process isn’t difficult to understand because it isn’t as many parts to the process. Glucagon also finds itself located in the pancreas along side insulin. The action of glucagon is that it causes

Control by hormones. What are the two hormones that regulate the pancreatic secretion? And how does each regulate it? A) Insulin and Glucagon B) Your pancreas constantly monitors and controls your blood sugar levels using the two hormones‚ Insulin and Glucagon. When your blood sugar levels rise after a meal your pancreas releases insulin. Insulin allows glucose to be taken into the cells of your body where it is used for energy. It also allows glucose to be converted to glycogen
