A)Pancreas
B)Liver
C)Ovary
D)Thyroid

Answer 1

In the vertebrates, this organ plays a critical role and has the main function of detoxifying various metabolites also involved in protein synthesis, and produces essential biochemicals that are helpful for digestion and growth. It is present in the right upper quadrant of the abdomen just below the diaphragm.

Complete answer:
-An endocrine system consists of a series of glands. These glands produce and then secrete loops of the hormones which are used by the body in the circulatory system.
-The hypothalamus, pituitary gland, and the pineal gland present in the brain make up the endocrine system. The thyroid and parathyroid gland present in the neck, the thymus is present between the lungs, the adrenal on the top of the kidney, and the pancreas behind the stomach.
-The glands that secrete the essential product by the way of a duct is known as exocrine glands.
-One of the largest, important, and least appreciated organs in the body is the liver. The liver comprises hepatocytes made up of epithelial cells having a unique configuration.
-The liver is one of such glands which is both exocrine and endocrine glands. It functions as an exocrine gland while secreting bile into the intestine and as an endocrine gland while working as a blood filter.
-Liver also performs the various functions which are not associated with the glands. It is a metabolic factory, helping in synthesizing and breakdown of a variety of substances.

Additional information:
Pancreas - its endocrine component composed of the islets of Langerhans helps in creating and releasing the important hormones directly into the bloodstream.
-Two important hormones of the pancreas are insulin, lower blood sugar, and glucagon which increase the blood sugar.
Ovary - besides producing ova, it also plays the major role of being an endocrine gland by secreting estrogen and progesterone hormones that are important to normal reproductive development and fertility.
Thyroid - it is made up of glands. Hence, a part of the endocrine system that helps in producing, storing, and releasing hormones into the bloodstream so that it can reach the body's cells.

So, the correct answer is, “Liver”.

Note:
-The liver secretes bile into the intestine and acts as an exocrine gland but it also acts as an endocrine gland and a blood filter.
-Many types of functions are performed by the liver which is not associated with the glands.
-It performs mini physiological processes such as regulation of systemic glucose and lipid metabolism.
