Final answer:
Jim's heart rate and respiratory rates have come down in the last 10 minutes due to the body's natural response to calming down after a period of physical exertion or stress. The sympathetic nervous system increases heart rate and respiratory rate during exercise or stress, while the parasympathetic nervous system slows them down when the body relaxes. This helps to supply enough oxygen to the muscles during activity and restore normal rates afterward.
Step-by-step explanation:
Jim's heart rate and respiratory rates have come down in the last 10 minutes due to the body's natural response to calming down after a period of physical exertion or stress. When the body is active or under stress, the sympathetic nervous system releases adrenaline, which increases heart rate and respiratory rate. Once the activity or stress is over, the parasympathetic nervous system takes over and helps to bring heart rate and respiratory rate back to normal.
During exercise or an intense activity, the sympathetic nervous system increases blood flow to the muscles, and the heart rate and respiratory rate increase to supply enough oxygen to the muscles. After the activity, the parasympathetic nervous system slows down the heart rate and respiratory rate as the body calms down and no longer needs as much oxygen.
For example, if Jim just finished running a race, his heart rate and respiratory rate would have been elevated during the race. But once the race is over and he stops running, his body will start to relax, and the parasympathetic nervous system will work to bring his heart rate and respiratory rate back to normal over time.
