*Insulin Response

*Ingestion/Digestion

*When we eat food, especially carbohydrates, the body converts that food into the preferred source of cellular energy, glucose.

*Absorption

*Glucose is then absorbed into the bloodstream to be delivered throughout the body.

*Pancreas

*The pancreas detects a rise in blood sugar and releases insulin.

*Insulin

*Insulin regulates (lowers) blood sugar levels by signaling the body cells to accept or allow glucose in to be used as energy (making ATP).

*Excess glucose

*Some excess glucose can be changed to glycogen and stored in the liver and muscle.

*Low blood/sugar

*As time passes since your last meal or after being active, your blood sugar/glucose levels drop.

*Glucagon

*The pancreas detects low levels of blood sugar and responds by releasing glucagon.

*Glucagon signals the liver and muscles to release glycogen.

*Glucagon changes glycogen back to glucose.

*And back to the beginning

*The pancreas detects glucose in the blood and releases insulin……………………
