Looking for online definition of transmural pressure gradient in the Medical Dictionary? transmural pressure gradient explanation free. Another possible theory is that the increase in end-expiratory lung volume, which may lead to increased transmural pressure

Transmural pressure is the difference in pressure between two sides of a wall or equivalent separator. For body vasculature or other hollow organs, see Smooth muscle#Contraction and relaxation basics For lungs, see Transpulmonary pressure Vascular smooth

For a given lung volume, the transpulmonary pressure is equal and opposite to the elastic recoil pressure of the lung. The transpulmonary pressure vs Volume curve of inhalation (usually plotted as Volume in function of Pressure) is different from that of exhalation.

By increasing lung volume, the transmural pressure gradient steadily increases, as shown for the whole lung in Figure 2.4. 6.3.1.1 Definition of the myogenic response Many blood vessels respond to transmural pressure elevation with constriction and to
