Quizplus · Accepted Answer

Arrows 1 and 3 represent an example of negative feedback control. Negative feedback control is a type of control system in which the output of the system is used to reduce the input. In this case, the output of the system is the concentration of glucose in the blood. When the concentration of glucose in the blood increases, the pancreas releases insulin. Insulin causes the cells in the body to take up glucose from the blood, which reduces the concentration of glucose in the blood.
