Answer: (EXAMPLES). Human body temperature - The hypothalamus of a human reacts to temperature fluctuations and responds accordingly. If the temperature drops, the body shivers to bring up the temperature and if it is too warm, the body will sweat to cool down due to evaporation.
Human blood pressure - When blood pressure increases, signals are sent to the brain from the blood vessels. Signals are sent to the heart from the brain, and heart rate slows down, thus helping blood pressure to return to normal.
Human metabolism - When a human is hungry, metabolism slows down to conserve energy and allows the human to continue living with less food.
Regulation of blood sugar in humans - When blood sugar rises, insulin sends a signal to the liver, muscles, and other cells to store the excess glucose. Some is stored as body fat, and other glucose is stored as glycogen in the liver and muscles.
Production of human red blood cells (erythropoiesis) - A decrease in oxygen is detected by the kidneys and they secrete erythropoietin. This hormone stimulates the production of red blood cells.
Explanation: Since we all know, A negative feedback loop is a reaction that causes a decrease in function. It occurs in response to some kind of stimulus. Often, it causes the output of a system to be lessened; so, the feedback tends to stabilize the system. This can be referred to as homeostasis, as in biology, or equilibrium, as in mechanics.
