The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. When a person walks, he or she breathes at a fairly slow rate. However, when he or she starts running, the oxygen requirement of the body increases, and the body is signaled to increase the rate at which the person breathes. Which body system interacts with the respiratory system to signal that the body's oxygen requirement has changed? A. musculoskeletal B. excretory C. nervous D. digestive
Question
The respiratory system is responsible for taking in oxygen and releasing carbon dioxide. When a person walks, he or she breathes at a fairly slow rate. However, when he or she starts running, the oxygen requirement of the body increases, and the body is signaled to increase the rate at which the person breathes. Which body system interacts with the respiratory system to signal that the body's oxygen requirement has changed? A. musculoskeletal B. excretory C. nervous D. digestive
Solution
The body system that interacts with the respiratory system to signal that the body's oxygen requirement has changed is the nervous system. So, the answer is C. Nervous.
Here's why: The nervous system controls the rate of respiration based on the body's needs. When you start running, your muscles need more oxygen to produce energy, so they send a signal to your brain. Your brain, in turn, sends a signal to your respiratory system to increase your breathing rate. This allows more oxygen to be taken in and more carbon dioxide to be expelled, meeting the increased oxygen demand of your body.
