Which of the following statements accurately describes the role of chemoreceptors in respiration regulation?
Chemoreceptors detect changes in oxygen levels and adjust respiration accordingly.
Chemoreceptors are only found in the peripheral nervous system.
Chemoreceptors respond solely to carbon dioxide levels.
Chemoreceptors are not involved in the regulation of respiration.
Answers (1)
Chemoreceptors are specialized sensory receptors that track chemical alterations in the body, such as variations in pH, carbon dioxide, and oxygen levels. Two different types of chemoreceptors are involved in controlling respiration: central chemoreceptors found in the brain's medulla oblongata and peripheral chemoreceptors found in the carotid bodies and aortic bodies.
Although chemoreceptors do react to variations in carbon dioxide levels, it is significant to remember that they also play a significant part in detecting variations in oxygen levels. Chemoreceptors are triggered and send signals to the brain's respiratory centers when blood oxygen levels drop (hypoxia), which causes an increase in breathing rate and depth. By doing this, the oxygen delivered to the tissues is increased.
Hence, the correct answer is option 1.
