insulin

Definition

Insulin is a hormone produced by the beta cells of the pancreatic islets in the endocrine pancreas, crucial for regulating blood glucose levels. It facilitates the uptake of glucose by cells, thereby lowering blood sugar.

Analogy

Think of insulin as a key that unlocks doors to your body’s cells. Just as a key permits entry into a locked room, insulin allows glucose (sugar) from the bloodstream to enter cells, providing them with energy to function properly.
