2) adrenal medulla
3) thyroid gland
4) parathyroid gland
5) pancreas islets
6) thymus glands
7) pineal gland
8) pituitary gland

Answer 1

All glands listed (adrenal cortex, adrenal medulla, thyroid gland, parathyroid gland, pancreas islets, thymus gland, pineal gland, and pituitary gland) are part of the endocrine system, which regulates bodily functions through hormone secretion.

Step-by-step explanation:

All of the glands listed are part of the endocrine system, which includes 1) the adrenal cortex, 2) the adrenal medulla, 3) the thyroid gland, 4) the parathyroid gland, 5) the pancreas islets (also known as pancreatic endocrine cells), 6) the thymus gland, 7) the pineal gland, and 8) the pituitary gland. These glands secrete hormones directly into the bloodstream, which are then carried to various organs and tissues within the body to regulate a multitude of bodily functions. The pituitary gland is often referred to as the 'master gland' of the endocrine system due to the fact that most of the hormones it produces control other endocrine glands.
