Normal dimensions of the human heart for livepersons can be determined noninvasively usingmagnetic resonance imaging (mri) or (2de). (s. kaul, et al., measurement of normal left heart dimensionsusing optimally oriented mr images, am. j. radiol. 146: 7579, 1986.) during systole the left ventricular cavity has a diameter of about34 mm and the wall thickness is about 16 mm. if systolic pressure is 130 mmhg, estimate thewall tension (5 points) assuming that the wall stress is constantand that the ventricle is a sphere of thedimensions given. estimate the wall stress(5 points).
