ANATOMY

Detailed explanation-1: -Glucagon is a hormone that your pancreas makes to help regulate your blood glucose (sugar) levels. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels.

Detailed explanation-2: -While glucagon keeps blood glucose from dropping too low, insulin is produced to keep blood glucose from rising too high. The two hormones counterbalance each other to stabilize blood glucose. When blood glucose levels fall too low (low blood glucose), the pancreas pumps out more glucagon.

Detailed explanation-3: -’Alpha cells’ in the islets of Langerhans produce another important hormone, glucagon. This has the opposite effect to insulin, by helping release energy into the bloodstream from where it is stored, thus raising blood sugar levels.

Detailed explanation-4: -The liver both stores and manufactures glucose depending upon the body’s need. The need to store or release glucose is primarily signaled by the hormones insulin and glucagon.

Detailed explanation-5: -In the retina, as in systemic metabolic pathways, insulin has effects opposite those of glucagon: Insulin increases, whereas glucagon decreases, the proliferation of neural progenitor cells at the margin of the postnatal chick retina.
