The tangential wall stress and the tangential elasticity modulus at pressures from 0 to 200 mm Hg were calculated from pressure-volume diagrams of 27 human thoracic aortas aged 22 to 85 years. The relative volume increase of the aortas between 0 and 100 mm Hg decreased linearly from about 190% at age 20 to about 40% at age 85, whereas the elasticity modulus at 100 mm Hg increased linearly from 10 kg/cm at age 20 to 42.5 kg/cm at age 85. The decrease of the distensibility of the aortic wall with… CONTINUE READING
