MICROANATOMY

Detailed explanation-1: -Insulin helps blood sugar enter the body’s cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use. Blood sugar enters cells, and levels in the bloodstream decrease, signaling insulin to decrease too.

Detailed explanation-2: -Insulin acts like a key, opening body cells so that glucose can enter the cell to provide a source of energy. Insulin is like the key to a car. A car needs fuel to run, but the key provides the spark that releases the fuel. In your body, insulin is used to “spark” the use of glucose as fuel in your cells.

Detailed explanation-3: -Insulin regulates glucose levels in the bloodstream and induces glucose storage in the liver, muscles, and adipose tissue, resulting in overall weight gain.
