Exocrine vs Endocrine Glands – Key Differences

Difference between Exocrine and Endocrine Glands - Exocrine vs Endocrine Glands

Exocrine glands are those equipped with ducts which allow cells to secrete their product through these ducts, so that they are released onto the surfaces of the targeted organs or cells. The cells in the exocrine glands are connected to the epithelium covering them with small tubular ducts that transport the secretions to the target locations. Exocrine glands’ secretions are not mixed into the bloodstream, as some of these substances could even cause harm in the blood if they are released.
