The answer is: It controls muscle contraction.
The nervous system influences the respiratory system through controlling muscle contraction.
The correct answer is: It controls muscle contraction.
The nervous system influences the respiratory system by controlling muscle contraction. Specifically, the autonomic nervous system, which is a division of the peripheral nervous system, regulates the muscles that are involved in breathing, such as the diaphragm and the intercostal muscles. The autonomic nervous system is further divided into the sympathetic and parasympathetic divisions, which have opposing effects on the respiratory muscles.
During inhalation, the sympathetic division activates and stimulates the contraction of the muscles, causing the lungs to expand and air to be drawn in. On the other hand, during exhalation, the parasympathetic division slows down the activity of the respiratory muscles, leading to relaxation and the expulsion of air from the lungs.
Overall, the nervous system plays a crucial role in controlling the respiratory system, ensuring that we can inhale oxygen and exhale carbon dioxide effectively.
