Pancreas: This is the organ in the body that contains cells called the beta-cells which are the cells that make insulin. The beta cells are sensitive to glucose, so as the glucose levels in the blood rises due to food intake, the beta-cells are stimulated to release insulin which then travels to the bodies cells, stimulates the insulin receptors to allow the bodies cells to take up glucose from the blood to be used as energy, thereby lowering blood glucose levels.
The pancreas also has cells called alpha-cells which make the hormone glucagon, which is the hormone that your body will release when your blood sugar levels go too low (hypoglycaemia). The pancreas also contains other cells that help with digestion.
Premix insulin: this is an insulin that you can inject that contains a short-acting (bolus) insulin and a longer-acting (basal) insulin in one injection. Premix insulin can be injected once, twice, or three times per day depending on what your requirements are. Premix insulin is normally injected immediately before the meal. Your health care provider will advise you on how to administer your premix insulin.
