Final answer:
The pancreas is a dual-function gland acting as both an exocrine and endocrine gland. It releases digestive enzymes and hormones like insulin and glucagon. The statement that is not true about the pancreas is that it uses feedback to control calcium.
Step-by-step explanation:
The pancreas is a dual-function gland, acting as both an exocrine gland and an endocrine gland. The exocrine function involves the release of digestive enzymes into the small intestine through ducts. The endocrine function involves the release of hormones, such as insulin and glucagon, directly into the bloodstream to regulate glucose metabolism.
The statement that is not true about the pancreas is c. It does not use feedback to control calcium. The pancreas primarily regulates glucose levels through the release of insulin and glucagon.
