Endocrine glands
Glands that secrete hormones do that into the blood, not into ducts. Hormones are not secreted into ducts. glands that secrete into ducts are called exocrine glands. Glands that secrete hormones are endocrine glands.
Ductless glands are part of the endocrine system. The endocrine glands secrete hormones. Because they have no ducts they secrete their hormones directly into the circulatory system.
No. Exocrine glands have tubes (ducts) leading from them to some other body part or cavity. Endocrine glands are ductless and secrete their substances.... mostly hormones..... into the intercellular space and these hormones are then picked up by the bloodstream and transported throughout the body to where they are needed.
Because an endocrine glad does not have a tube through which it delivers hormone to the body. They just release their hormones into the space around the gland, which diffuse into the blood stream.
Hormones.
Ductless glands are glands that secrete there product directly onto a surface rather than through a duct.
The glands in this category secrete their products, the hormones, into the blood stream, rather than via ducts. They have no ducts. In contrast, the salivary glands secrete saliva into the mouth cavity, rather than the blood stream. These are exocrine glands.
Endocrine glands are glands which secrete oil, sweat, enzymes into ducts. Example: sweat glands, sebaceous glands, digestive gland, mucous. Correction! Exocrine glands are those which secrete to the outside (can still be inside the body- for example hormones involved in digestion) which have ducts and secrete oil- sebaceous glands. Endocrine glands secrete to hormones the "inside" and DO NOT have ducts, they are ductless.

Endocrine Glands are a type of ductless organ that produce hormones

Endocrine glands. This is the basis of your endocrine system which secretes hormones into the blood stream directly without using ducts.
