PATHOLOGY

Detailed explanation-1: -The endocrine glands do not have ducts to carry their product to a surface. They are called ductless glands.

Detailed explanation-2: -Endocrine glands do not have ducts. Their secretions (hormones) are secreted into the blood stream. Because of this, the hormones can act over long distances, and reach any organ in the body to co-ordinate activity. Often there is a specific ‘target’ organ that the hormone acts on.

Detailed explanation-3: -Endocrine glands do not have ducts. This allows the hormones to act over long distances. The hormones are able to reach any target organ that it needs to act on. The glandular epithelium that secrete substances through ducts are called exocrine glands.

Detailed explanation-4: -The key difference between the two types is that, whereas exocrine glands secrete substances into a ductal system to an epithelial surface, endocrine glands secrete products directly into the bloodstream [1]. Exocrine secretions form in the acinus, a small cluster of cells at the origination of glandular ducts.

Detailed explanation-5: -Glands without ducts are called “ductless” or “endocrine” glands. They release their secretions directly into the bloodstream. Pituitary is the master endocrine gland which regulates the secretions of other endocrine glands such as pancreas, thyroid gland, gonads, adrenal gland, etc.
