Answer:
The difference between an Endocrine and an Exocrine Gland is that Exocrine Gland are those glands that pour their product of secretion to the outside of the body ( have secretion channels) and Endocrine Glands are those that pour their product of secretion (hormones) into the bloodstream ( have no secretion channels).
Explanation:
The glands are structures that can be constituted by one or several cells, and that are formed from epithelial tissue. Their function is to secrete various substances, such as hormones, and they are classified as endocrine and exocrine, according to the place where they discharge their secretions.
The Endocrine Glands are very vascular structures, that is, irrigated by a large network of blood capillaries, thin and porous walls. These glands produce hormones that are poured directly into the bloodstream and transported by the blood vessels to the target tissues, where they come to perform their function. According to the chemical nature of the hormones produced by the endocrine glands, the organelles of the cells that constitute them can reach different degrees of development. For example the pancreas secretes insulin, which allows the body to regulate blood sugar levels.
The Exocrine Glands secrete substances through ducts directed to the surface of the body or to the interior of some organs. For example, exocrine glands are mucus-producing goblet cells, present in mucosal epithelia such as the lining of the intestine, and the sweat, sebaceous, and mammary glands. Tears are also produced by exocrine glands.
