MICROANATOMY

Detailed explanation-1: -Glucagon increases blood sugar levels, whereas insulin decreases blood sugar levels. If your pancreas doesn’t make enough insulin or your body doesn’t use it properly, you can have high blood sugar (hyperglycemia), which leads to diabetes.

Detailed explanation-2: -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-3: -Incretin Hormones Nutrients in the GI tract stimulate the secretion of hormones known as incretins which amplify glucose-induced insulin release.
