Homeostasis refers to the
arrangement of atoms and molecules at the chemical level of organization.
existence of a stable internal environment.
interdependent, interconnected organ systems of the body.
shared environment of cells, tissues, organs, and systems in the body.
Homeostasis regulation usually involves a receptor, a __________, and an effector.
stimulus
response
control centre
feedback
The regulatory mechanism that occurs when a variation outside of normal limits triggers an automatic response that corrects the situation is
negative feedback.
positive feedback.
effector regulation.
receptor regulation.
When the initial stimulus produces a response that reinforces the stimulus, the mechanism is called
thermoregulation.
positive feedback.
set-point integration.
negative feedback.
When body temperature rises, a center in the brain initiates physiological changes to decrease body temperature. This is an example of
positive feedback.
set-point integration.
receptor regulation.
negative feedback.
Increasingly forceful labor contractions that lead to childbirth are an example of
negative feedback.
positive feedback.
effector regulation.
receptor regulation.
