Answer 2

Insulin is secreted by β-cells of pancreas.

* The Islets of Langerhans in the pancreas have specialised cells such as ∝-cells, β-cells and δ-cells or D cells.

These are responsible for the secretion of important hormones.

* ∝-cells- secrete glucagon that stimulates the release of glucose from cells.

* β-cells- secrete insulin that stimulates the uptake of glucose into the cells.

These two hormones together regulate the level of glucose in the body.

* δ-cells- secrete somatostatin that regulates other functions.
