Q. According to the attached passage, why is the output of the negative feedback loop for oxygen demand located at the diaphragm?
Hypoxia is a term used to describe a set of symptoms, including fatigue, headaches, and confusion, that arise due to oxygen deprivation. When visiting the Rocky Mountains in the US, where the partial pressure of oxygen is approximately 15% lower than what one is accustomed to on the coast, these symptoms can be induced. The body has a limited tolerance for variations in environmental oxygen levels as it lacks a significant capacity to store oxygen, which is continuously consumed to maintain energy homeostasis.
In response to oxygen deprivation, the body increases the rate of breathing and the volume of each breath. This adjustment is part of a negative feedback loop that helps maintain homeostasis. The carotid body, located inside the carotid artery, serves as the sensor for detecting oxygen concentrations. The information gathered by the carotid body is then processed in the respiratory centers (RCs) of the brainstem's medulla. Ultimately, the output of this feedback loop is directed to the diaphragm, which plays a key role in respiration.
  • a)
    The diaphragm facilitates inhalation and exhalation.
  • b)
    The diaphragm constricts the carotid artery and closes the loop.
  • c)
    The diaphragm signals neurons to stimulate breathing.
  • d)
    The diaphragm opens the nasal passages.
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

The diaphragm is the primary muscle involved in respiration.
The diaphragm is a large, dome-shaped muscle located at the base of the thoracic cavity, separating the chest cavity from the abdominal cavity. It plays a crucial role in the process of breathing. During inhalation, the diaphragm contracts and flattens out, causing it to move downward. This action increases the volume of the thoracic cavity, leading to a decrease in pressure within the lungs. As a result, air is drawn into the lungs. During exhalation, the diaphragm relaxes and moves upward, reducing the volume of the thoracic cavity and causing air to be expelled from the lungs.
The diaphragm's contraction and relaxation create changes in the thoracic cavity's volume, facilitating the flow of air into and out of the lungs. Therefore, it is considered the primary muscle responsible for the mechanical aspect of respiration.
