Lung stretch receptors are sensory structures located within the lungs that detect changes in lung volume. They play a crucial role in regulating breathing and maintaining respiratory homeostasis. These receptors, also referred to as pulmonary stretch receptors, are responsible for initiating the lung inflation reflex, which helps prevent over-inflation of the lungs during inspiration. Their primary function is to sense and transmit signals to the brain, signaling the need to adjust breathing patterns. Synonyms for lung stretch receptors include pulmonary stretch receptors, lung distension receptors, and pulmonary mechanoreceptors. Regardless of the terminology used, these receptors are essential for maintaining optimal lung function and ensuring efficient oxygen exchange within the body.
