Thyroid and Parathyroid Glands are Antagonistic.
-Thyroid gland produces Calcitonin, which lowers blood calcium levels.
-Parathyroid gland produces Parathyroid Hormone (PTH), which raises blood calcium levels.
There are very many "antagonistic" hormones that are produced by endocrine glands.
It creates insulin and secretes digestive enzymes.
The gonads are the testes and ovaries. Both also have endocrine (gland) functions.
testes are the two endocrine glands in the scrotal sac of a male.
Two components of the endocrine system are hormones (chemical messengers that regulate various bodily functions) and glands (organs that secrete hormones into the bloodstream).
Adrenal Glands

Yes, an adrenal gland is an endocrine gland. There are two adrenal glands: one sits above each kidney.
The structural modification in the salivary glands that allow them to carry out their functions are the different sized glands and their location. The larger of the two glands is the parotid gland. The smaller of the two salivary glands is the submandibular gland.
The two categories of glands based on their method of secretion are exocrine glands, which secrete their products into ducts that lead to the external environment or another surface, and endocrine glands, which secrete hormones directly into the bloodstream.
The adrenal medulla and the pituitary gland are endocrine glands made of a mixture of nervous and epithelial tissues. The adrenal medulla is part of the adrenal glands located on top of each kidney, while the pituitary gland is often referred to as the "master gland" because it controls several other endocrine glands in the body.
Two endocrine glands are the hypothalamus gland and the Thyroid. The hypothalamus gland is located in the center area of the brain. It's functions are to stimulate and inhibit the release and secretion of the anterior pituitary gland. The thyroid gland is located around the esophageal area and it's functions are to release thyroxine and triiodothyronine, also know as t4 and t3 and calcitonin. The release of these hormones stimulate the energy metabolism of all cell and inhibits the breakdown of bone; causing a decrease in blood calcium concentraion.
