The pancreas aids in the digestive process, as well as helps regulate blood sugar levels. During digestion, the pancreas secretes pancreatic juice. This fluid contains certain compounds that help to neutralize the acidity in the digestive tract. It also contains enzymes, which help breakdown food and absorb it. In the endocrine system, the pancreas produces hormones, including insulin and glucagon. Insulin helps lower blood sugar levels, whereas glucagon helps to raise them.
