Document Summary
Blood vessels are controlled by the sympathetic division of the ans as well as by hormones ssuch as angiotensin ii. The endocrine system is a very diffuse system: any tissue/organ containing endocrine cells is part of the endocrine system. Exocrine glands secrete products into ducts or lumens or to the outer surface of the body. Endocrine glands secrete products into interstitial fluid, which diffuse into blood. The endocrine system does/does not include any exocrine glands. Some organs have both exocrine and endocrine potions. Only the endocrine portion of an organ functions as part of the endocrine system. Local hormones can act as autocrine and paracrine signals at the same time. Peptide and protein hormones are hypothalamic releasing and inhibiting hormones. Hormones are released from glands in response to internal or external changes. All hormones have 1 or more types of target cells.
