Answer
Exocrine glands deliver their secretions to targets by ducts or tubes. On the other hand, endocrine glands have their have their secretion transported by the blood stream. Examples of exocrine glands
are sweat glands, pancreas, salivary glands and other digestive glands.. Examples of endocrine glands are the pituitary, the thyroid gland, the adrenals and the pineal gland.
Work Step by Step
Exocrine glands secrete products into tubes that carry them into body cavities, into the lumen of organs or distribute them over body surfaces. Salivary glands discharge into the oral cavity and sweat glands and sudoriferous glands discharge their secretions over the epidermal surface.
Endocrine glands secrete their hormones into interstitial fluid around glands. The hormones diffuse from the interstitial fluid into blood capillaries , and the blood stream carries the hormones to the target organs. Adrenal catecholamines hormones(neurotransmitters) and pituitary hormones are distributed in this way.
