    Hi I need help in this question I don’t understand can you please help. Explain how the body uses hormones to maintain blood sugar levels

    • koko koko 2 years ago

      When the blood glocose level is high :Hormones (insuline) are secreted by the pancreas, then it goes to the liver where it causes the liver to convert the glucose to glycogen… And the glucose level is brought back to normal.

    • koko koko 2 years ago

      When the glucose level is low the pancreas secreat glucagon which goes to the liver and causes it to convert the stored glycogen to glucose and then I glucose is passes to the blood stream and this is how the blood glucose Is back to normal again
