Answer:
This question is incomplete, the question is asking to match each description with its gland.
1. Pituitary gland (hypophysis): The size and shape of a pea; produces hormones that stimulate other endocrine glands
2. Adrenal medulla: Is part of the sympathetic nervous system
3. Pancreas: Produces hormones that regulate glucose levels in the body
4. Parathyroid glands: Primary regulators of blood calcium levels
5. Thyroid gland: Produces the body's major metabolic hormones.
Explanation:
1. Pituitary gland is the gland known as the "master gland" because it produces hormones that coordinates the activities of other endocrine glands. The pituitary gland is shaped like a pea and functions to maintain the well-being of the body i.e. metabolism, growth etc.
2. Adrenal medulla is the inner part of the Adrenal gland, which is an endocrine gland located above the kidney. The adrenal medulla (a part of adrenal gland) is a part of the sympathetic nervous system which functions in control of blood pressure and heart rate.
3. Pancreas is a digestive organ that acts as a gland by secreting hormones that regulate glucose levels in the body. These hormones are insulin and glucagon
4. Parathyroid glands is an endocrine gland that produced the parathyroid hormone, which helps in the regulation of blood calcium ion levels.
5. Thyroid gland is an endocrine gland located in front of the neck. It produced series of hormones called thyroid hormones that functions in the body's metabolism
