• C. The endocrine pancreas consists of 1-2 million ‘Islets of Langerhans’.
• D. It is located above the kidney.

Answer 1

The correct option is D It is located above the kidney.

The pancreas is located below the stomach. The adrenal gland is located above the kidney.

The pancreas is a mixed gland. It acts both as an exocrine and an endocrine gland.

The endocrine pancreas is composed of 1-2 millions of ‘islets of Langerhans’. These are island-like tissues interspersed between the exocrine tissues of the pancreas.

There are two main types of cells in the islet of Langerhans, $\alpha$-cells and $\beta$-cells. The $\alpha$-cells secrete a hormone called glucagon, while the $\beta$-cells secrete insulin.
