pulmonary stretch receptors การใช้

• The apneustic center is inhibited by pulmonary stretch receptors.
• Sulfur dioxide blocks nerve signals from the pulmonary stretch receptors and abolishes the Hering Breuer inflation reflex.
• Pulmonary stretch receptors present in the smooth muscle of the airways respond to excessive stretching of the lung during large inspirations.
• Thus, an increase in pulmonary stretch receptor activity leads to inhibition of the CVMs and an elevation of heart rate ( tachycardia ).
• Chemoreceptor activity, however, also affects cardiovascular function either directly ( by interacting with medullary vasomotor centers ) or indirectly ( via altered pulmonary stretch receptor activity ).
