Exocrine glands maintain their contact with the surface by way of a duct, an
epithelial tube that conveys their secretion to the surface. The secretion maybe
released to the body surface, as in the case of sweat, mammary, and tear glands.

They do however have a high density of blood capillaries and secrete their products
directly into the blood. These secretions are called hormones.
