Final answer:
The adrenal medulla, pancreas, thyroid gland, and parathyroid glands are endocrine glands that produce hormones with various functions.
Step-by-step explanation:
The adrenal medulla is the gland that controls the flight-or-flight reaction. It produces hormones such as epinephrine (adrenaline) and norepinephrine (noradrenaline) that are involved in the stress response.
The pancreas is the gland that produces hormones that regulate glucose levels in the body. Insulin lowers blood glucose levels, while glucagon raises them.
The thyroid gland and parathyroid glands are the primary regulators of blood calcium levels in the body. The thyroid gland produces hormones such as thyroxine and triiodothyronine, which regulate metabolism. The parathyroid glands produce parathyroid hormone, which raises blood calcium levels.
