Consider statements about human physiology: 1. The pancreas secretes both digestive enzymes and hormones. 2. The liver secretes bile, which contains digestive enzymes. 3. The gall bladder stores and concentrates bile. Which are correct? MCQ with Answer and Explanation

The pancreas is a mixed gland; its exocrine part secretes digestive enzymes (trypsin, lipase, amylase), and its endocrine part (Islets of Langerhans) secretes hormones (insulin, glucagon). The liver continuously secretes bile, but bile does not contain digestive enzymes; it contains bile salts that emulsify fats. The gall bladder stores and concentrates this bile before releasing it into the duodenum. Thus, statements 1 and 3 are correct.
