ALL hormones by definition are secreted directly into the blood stream (and hence without the use of a duct). Glands that produce them are called endocrine glands. Major endocrine glands include the pituitary, thyroid, adrenal and pineal glands. Glands such as the pancreas have a "dual" function in that they secrete via a duct (exocrine function) as well as secreting hormones (endocrine function).
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.
The gland that has no duct and secretes its product directly into the blood is the endocrine gland. Examples of endocrine glands include the pituitary gland, thyroid gland, and adrenal gland.
the merocrine duct. and secretes in the "duct"
Yes, it secretes its products into a tube/duct.
Glands that secrete their contents into the blood stream. Examples Adrenal Gland and Thyroid Gland. Some glands are both duct/ductless. The Pancreas secretes several hormones into the blood stream and also secretes enzymes via ducts into the small bowel.
The type of gland that secretes its products continuously by exocytosis into a duct is called an exocrine gland. These glands, such as salivary glands and sweat glands, release their secretions directly into ducts that lead to the target area or surface. This process allows for a regulated and continuous flow of substances like enzymes, sweat, or saliva.
A simple branched gland has a single duct that divides into multiple branches within the gland. In contrast, a compound gland has multiple ducts that lead to a single secretory unit or multiple secretory units grouped together. Compound glands are typically larger and more complex in structure compared to simple branched glands.
Sebaceous glands are associated with hair follicles within the dermis.
The parotid gland secretes amylase which helps to break down starches in the first stages of mastication. It is located anterior to the ear, but doesn't participate in ear function.
The pancreas releases hormones glucagon and insulin into the blood stream like all other endocrine organs, but also releases digestive enzymes into the intestine. Since the intestine is considered 'outside' that is an exocrine function.

I think the student wanted to ask about the difference between an exocrine and endocrine gland but mistakened and wrote both the same. Exocrine gland differ from Endocrine gland because in case of exocrine glands ezymes are secreted by ducts carrying them to their site of actions but in case of endocrine hormones are secreted in body without ducts and are cariied by circulatory fluid of the organism.
