.When we exercise, our bodies begin to heat up due to the amount of stress we place on our muscles and organs. For example, when we run, our heart must pump blood to our muscles faster than usual to give our muscles enough oxygen to perform the task we are wanting to perform. To supply our blood with the proper amount of oxygen our lungs must expand and work faster than usual as well. The stress placed on those two organs and the muscles involved in the exercise causes our body to heat up. Our body also has an organ that has the job of trying to cool our body down during exercise. Research which organ that is and explain to me what that organ does to cool our bodies off during exercise.

Explanation:

Muscle Heat Production

To work, your muscles need energy, which they obtain by burning fuels such as fats and carbohydrates in a series of chemical reactions that produce heat. As your muscles warm up during your workout, blood circulating through the muscles is also warmed, producing a rise in core temperature. The amount of heat your muscles produce is related to the amount of work they perform. The more strenuous your workout, the more heat they produce. During very vigorous workouts, muscle heat production can increase 15 to 20 times above resting levels.

Thermoregulation

How high your temperature rises during your workout depends not only on how much heat your muscles produce, but also on how fast your body loses heat. In cold conditions, your body loses heat rapidly. In hot, humid weather, your body is less able to dissipate excess heat, making overheating more of a risk. A rise in core temperature to above 104 degrees Fahrenheit can result in life-threatening heat stroke, so your body has a number of mechanisms to keep your core temperature within fairly narrow limits, even during a strenuous workout.

Losing Heat

As your core temperature increases during your workout, blood is shunted away from your core to your skin, which allows your skin to radiate more heat, reducing your temperature. Sweating also helps to cool you. As sweat evaporates, it carries off excess heat. Because less sweat evaporates when the humidity is high, you're more likely to overheat in muggy weather than in dry conditions. As you become more fit with training, your body's ability to dissipate heat improves, a process called acclimatization. You begin sweating earlier in your workout, and at a lower temperature.
