It secretes juices containing enzymes that are capable of digesting all major types of food -- carbohydrates, fats and proteins. The pancreas is the first organ to begin digesting fats. It secretes pancreatic lipase, esterase and phospholipase, which break down chemically complex fats into simple, easy-to-absorb fats. Similarly, trypsin and carboxypolypeptidase break down proteins, and pancreatic amylase breaks down carbohydrates.
The hormones parathyroid hormone (PTH) and calcitonin help regulate blood calcium levels. Calcitonin, secreted by the thyroid gland inhibits osteoclasts and stimulates osteoblasts, thus decreasing blood calcium levels.Parathyroid hormone is secreted by the parathyroid glands, which are on the posterior side of the thyroid.Parathyroid hormone inhibits osteoblasts, stimulates osteoclasts, reduces the output of calcium by the kidneys and promotes the absorption of calcium by the small intestines, thus increasing blood calcium levels. deficiency of blood calcium is called hypocalcemia, and an excess of blood calcium is called hypercalcemia. Bone is the major storage site for calcium in the body, and movement of calcium into and out of bone helps to determine blood calcium levels.
