Examples include the thyroid gland, adrenal gland, and pituitary gland. Exocrine gland is a gland whose secretions are released externally through ducts into the skin, intestinal lumen, mouth, etc. They are distinct from the other type of gland, endocrine, in that exocrine gland secretions end up external to the body, while endocrine secretions go into the bloodstreaminternal. Sweat glands, for instance, are exocrine glands, and have specific ducts. The hormones released by the endocrine system are vital in regulating metabolism, tissue function. The hypophysis pituitary and the adrenals are examples of endocrine glands. Endocrine responses are slow because hormones must travel through the blood to reach their target organs. Also, the duration of the response is long because the hormone must be filtered out of the blood by the kidneys. A lot of people want to know the difference between endocrine and exocrine glands in terms of physiology and pathology. Difference between endocrine and exocrine compare the.
Although they are often made up of multiple cells, exocrine glands may be as small as a single cell. Goblet cells, for example, are singlecelled glands in the respiratory tract that produce mucus. Endocrine glands, on the other hand, release more than 20 major hormones directly into the bloodstream where they can be transported to cells in other parts of the body.
