Modeling Body Systems Quick Check 4 of 54 of 5 Items Question How does the nervous system influence the respiratory system?(1 point) Responses It controls muscle contraction. It controls muscle contraction. It regulates blood pressure. It regulates blood pressure. It regulates urine output. It regulates urine output. It stimulates defense against pathogens.
It controls muscle contraction.
The nervous system influences the respiratory system through the following ways:
1. It controls muscle contraction: The nervous system is responsible for initiating and regulating the contraction of muscles involved in the respiratory process, such as the diaphragm and intercostal muscles.
2. It regulates blood pressure: The nervous system helps regulate blood pressure, which indirectly affects the respiratory system by ensuring adequate blood flow to and from the lungs.
3. It stimulates defense against pathogens: The nervous system can stimulate immune responses that help protect the respiratory system from harmful pathogens.
To determine how the nervous system influences the respiratory system, we need to understand the functions of both systems and how they interact.
The nervous system is responsible for controlling and coordinating the activities of the body. It includes the brain, spinal cord, and nerves. On the other hand, the respiratory system is responsible for the exchange of gases (oxygen and carbon dioxide) between the body and the atmosphere. It consists of the lungs, bronchi, and other respiratory structures.
In the context of the given options, the correct answer is "It controls muscle contraction." This is because the nervous system controls the muscles involved in the process of breathing. The diaphragm, which is a key muscle for breathing, receives signals from the nervous system to contract and relax. This contraction and relaxation of the diaphragm enable inhalation and exhalation.
Therefore, the nervous system influences the respiratory system by controlling the muscles involved in breathing.
