Is it true that the exocrine glands have ducts and they pour their secretion into the blood?

The given statement is false.

Exocrine glands secrete their products into ducts, which then deliver the secretion to the body's exterior or to a body cavity, but not into the blood.

In contrast, endocrine glands are ductless glands that secrete their products (hormones) directly into the bloodstream, which then carry the hormone to target cells or organs throughout the body.
