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.
endocrine gland
the merocrine duct. and secretes in the "duct"
A simple branched gland has only one duct with more than one are that secretes into that duct. Compound glands have multiple ducts leading into the main 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.

Sebaceous glands are associated with hair follicles within the dermis.
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.
