Question

Blood sugar level can be decreased by

• A. Insulin given from mouth
• B. Glucagon given through mouth
• C. Intravenous injection of insulin
• D. Intravenous injection of glucagon

Answer 1

The correct option is C Intravenous injection of insulin

Intravenous injection of insulin is the injection of insulin directly into the blood. It is used to control blood sugar in people, where the body does not make insulin and therefore cannot control the amount of sugar in the blood. Insulin cannot be taken orally because the oral dose of insulin degenerates in the stomach by digestive enzymes. Thus, the correct answer is option C.
