Pulmonary chemoreceptors and mechanoreceptors
High Yield Notes
2 pages
Summary
Pulmonary chemoreceptors are specialized sensory cells located in the medulla, the aortic and carotid bodies, which detect changes in the concentration of carbon dioxide and oxygen in the blood. There are also pulmonary mechanoreceptors, which are specialized sensory cells located in the lungs and the airway smooth muscles. They respond to changes in lung stretch or pressure. Both the pulmonary chemoreceptors and mechanoreceptors work together to help maintain proper gas exchange and lung function during exercise and other activities that can alter the body's oxygen and carbon dioxide levels.
