Document Summary
Need system to respond in change in environment. If a system is disturbed, there is a coordinated response in the body to maintain a steady state. Coordinated redirection of resources to set new homeostatic conditions. Establishment of a new steady state based on a change in physiologic state within the animal. System of chemical communicators in regulatory biology. Body can respond and can monitor a response. Need systems that can be turned on and turned off. Must be able to turn system off. Synthesized and secreted from neurons and released across a synaptic. Fatty acid secreted from specialized glands into the air (animal to animal) Chemical secreted from specialized ductless glands directly into the bloodstream. Synthesized and secreted from neurons directly into the bloodstream. Chemicals secreted from one cell that has its effect in nearby cells in an autocrine or paracrine mechanism. Have an endocrine effect on nearby cells without having to go into the bloodstream.
