How might abnormalities in an animal's anatomy or physiology have a negative impact on its health and well-being? The functions of the parts of an animal's body are extremely interrelated. Therefore an abnormality with the anatomy or physiology of one part can affect other parts.
Learning Objectives. By the end of this section, you will be able to: List the components of a homeostatically controlled system. Discuss the role of homeostasis in the human body. Contrast negative and positive feedback, giving one physiologic example of each mechanism.
Identify and define the four interacting components that maintain homeostasis in feedback loops. Compare and contrast negative and positive feedback loops. Explain how negative feedback controls body temperature.
Discuss the role of homeostasis in healthy functioning. Contrast negative and positive feedback, giving one physiologic example of each mechanism. Maintaining homeostasis requires that the body continuously monitor its internal conditions.
Negative feedback loops, in conjunction with the various stimuli that can affect a variable, typically produce a condition in which the variable oscillates around the set point. For example, negative feedback loops involving insulin and glucagon help to keep blood glucose levels within a narrow concentration range.
