Question

exercise causes many factors of negative feedback to jump start into action. how exercise affects these factors can be determined by measuring and observing certain conditions of the human body. exercise can increase the pulse rate, change skin color around the arms and face, increase perspiration, increase external body temperature, increase breathing rate, heart rate and blood pressure. a stimulus such as elevated pulse rate can lead to a reaction by the body causing a negative feedback response that will return the pulse rate to normal. hypothesis: how will the human body attempt to maintain homeostasis during exercise? materials: stopwatch thermometer

Explanation:

The human body uses negative - feedback mechanisms to maintain homeostasis during exercise. For example, when the pulse rate increases due to exercise, the body's negative - feedback response works to return it to normal. This can involve physiological changes such as increased sweating to regulate body temperature, and adjustments in breathing and heart rate to meet the body's oxygen and energy demands.

Answer:

The human body uses negative - feedback mechanisms like adjusting pulse rate, sweating, breathing and heart rate to maintain homeostasis during exercise.
