What is the primary function of insulin in the body?

• A. Increase blood pressure
• B. Regulate blood glucose levels
• C. Enhance muscle growth
• D. Stimulate digestion

Answer: (B)

The primary function of insulin in the body is to regulate blood glucose levels. Insulin is a hormone produced by the pancreas that plays a crucial role in maintaining homeostasis of glucose in the bloodstream. When you eat, carbohydrates are broken down into glucose, which enters the bloodstream. Insulin facilitates the uptake of this glucose into cells, where it can be used for energy or stored as glycogen in the liver and muscle tissues for future use. By promoting the absorption of glucose, insulin helps to lower blood glucose levels after meals and prevents hyperglycemia (high blood sugar). This regulatory function is vital for overall metabolic health, which is why understanding insulin's role is key in areas like diabetes management and metabolic health.
