The Role of Insulin in the Human Body

Animation Description: This patient-friendly animation describes the main role of insulin in the human body.

When food is ingested, it travels along the digestive tract where it is broken down into its component nutrients in order to be absorbed into the bloodstream. One such nutrient is glucose, a simple sugar.

Glucose gets absorbed by the stomach and intestines and then enters the bloodstream. It travels through the circulation to all body cells.

Once absorbed into the bloodstream, glucose circulates causing the blood sugar level to rise. An increased level of blood sugar sends a signal to the pancreatic beta cells, which respond by secreting the hormone insulin into the circulation.

Insulin is necessary for glucose to reach and be used by several important target tissues throughout the body. These include the liver, muscle, and adipose tissue. Insulin is necessary to keep blood glucose levels stable in the body.

Circulating insulin binds to specific insulin receptors located on the cell membrane of tissue cells throughout the body.

Upon binding, a signal is sent to the nucleus of the cell, instructing it to transport glucose channels to the cell surface. These channels allow glucose to enter the cell.

Glucose enters the cell through a process called facilitated diffusion.

The brain can take glucose without the need for insulin.

In conclusion: Glucose and only glucose is the reason of diabetes. Not fat nor fructose

How does the signal goes to pancreas,I mean how does it get known that glucose level is increased in blood stream?

Very simplified explanation of One of the things Insulin does in the body

Mike Cola

Mike Cola . 2 years ago

Insulin is the storage hormone that takes sugar (glucose/fructose) out of the blood and helps store it in the form of glycogen in your muscles and liver....The problems start when you eat too many carbohydrates or food in general, and your glycogen levels are full but you still keep eating more carbs. All excessive carbs that can no longer be stored or burned immediately are then converted into body fat. Now, if you keep on eating too many carbohydrates over and over again and your pancreas keeps on making insulin to take the sugar out of your blood, eventually you will become Insulin Resistance....Your body will no longer respond properly to insulin and that can lead to a number of health issues like metabolic syndrome, diabetes, pre-diabetes and weight gain.

Thank you. So essentially there are always GLUT channels present in beta cells in order to detect the change in glucose levels in the blood. GLUT 1 is for erythrocytes right?

Very nice video but for highschool. For Medicine or Pharmacy studies the infos are not so deep. It should explains also the mechanism of glucose signaling at β-cells and also the phosphorilation of intracellular proteins which lead at GLUT translocation. But it remains a very nice video! Thanks for uploading!

This is not the role of insulin in the whole human body . you should also underline the action that it has on adipose tissue favouring the accumulation of lipid droplets and on central nervous system decreasing appetite
