Pancreas is a yellowish, leaf like mixed gland which is located posterior to the stomach in abdominal cavity. It is composed of two parts namely, an exocrine part and an endocrine part.

The exocrine part secretes a slightly alkaline juice, which is known as pancreatic juice. This pancreatic juice contains trypsinogen, chymotripsinogen, and carboxypeptidase (proenzyme) and sodium bicarbonate.

Pancreatic lipase, pancreatic-amylase, DNase and RNase are secreted in active form.
