Final answer:
The feedback loop in the communication process consists of a sensor, control center, and effector. These components help maintain homeostasis by regulating physiological values within a normal range. Examples of negative feedback loops include body temperature regulation and control of blood glucose levels.
Step-by-step explanation:
The feedback loop consists of several components in the communication process. In a negative feedback loop, the components include a sensor, control center, and an effector. The sensor monitors a physiological value and reports it to the control center, which compares the value to the normal range. If the value deviates too much, the control center activates an effector to reverse the situation and return the value to the normal range.
