What is the primary role of the peripheral chemoreceptors in maintaining blood pressure?
Understand the Problem
The question is asking about the function of peripheral chemoreceptors and how they help maintain blood pressure. It presents multiple choice options that describe different roles of these receptors.
Answer
Peripheral chemoreceptors regulate blood pressure by detecting changes in blood oxygen, carbon dioxide levels, and pH.
Peripheral chemoreceptors primarily respond to changes in blood oxygen, carbon dioxide levels, and pH, initiating reflexes such as increased ventilation and sympathetic stimulation to regulate blood pressure and maintain homeostasis.
Answer for screen readers
Peripheral chemoreceptors primarily respond to changes in blood oxygen, carbon dioxide levels, and pH, initiating reflexes such as increased ventilation and sympathetic stimulation to regulate blood pressure and maintain homeostasis.
More Information
Peripheral chemoreceptors are located in the carotid and aortic bodies and are crucial for immediate responses to changes in blood chemistry, affecting ventilation and blood pressure via autonomic nervous system actions.
Tips
A common mistake is to confuse the role of peripheral chemoreceptors with central chemoreceptors; peripheral chemoreceptors are more sensitive to oxygen levels, whereas central chemoreceptors primarily respond to carbon dioxide and pH changes.
