Insulin
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
Insulin is a hormone made by the pancreas that allows your body to use (glucose) from carbohydrates in the food that you eat for energy or to store glucose for future use. Insulin helps keeps your blood sugar level from getting too high (hyperglycemia) or too low (hypoglycemia). The cells in your body need sugar for energy. However, sugar cannot go into most of your cells directly. After you eat food and your blood sugar level rises, cells in your pancreas (known as beta cells) are signaled to release insulin into your bloodstream. Insulin then attaches to and signals cells to absorb sugar from the bloodstream. Insulin is often described as a “key,” which unlocks the cell to allow sugar to enter the cell and be used for energy.

This video explains insulin, a hormone made by the pancreas. It covers how insulin allows the body to use glucose from carbohydrates for energy or store it for future use, how beta cells in the pancreas release insulin when blood sugar rises after eating, and how insulin signals cells to absorb sugar from the bloodstream.

- Defines insulin as a hormone made by the pancreas
- Covers insulin helping keep blood sugar from getting too high or too low as described
- Describes beta cells releasing insulin when blood sugar rises after food
- Describes insulin as a key that unlocks cells to allow sugar to enter and be used for energy as presented
