What is the pancreas? Mention the major secretions of the pancreas that are helpful for digestion.
Ans:
Pancreas is a compound gland, i.e. both endocrine and exocrine glands. It is situated between the limbs of the U-shaped duodenum. It is a mixed gland since it contains both exocrine and endocrine parts. The exocrine portion of this gland secretes the pancreatic juice released in the duodenum and containing digestive enzymes. The digestive enzyme is alkaline and neutralizes the acid present in the food coming from the stomach into the duodenum. Whereas the endocrine portion of this gland secretes hormones: insulin and glucagon that helps maintain the level of sugar in the blood.
