Describe the pressure-volume curve of the left ventricle
Explain why the walls of the atria are thinner than those of the ventricles, and why the wall of the right ventricle is relatively thin when compared to the wall of the left ventricle.
In dilated cardiomyopathy of the left ventricle, the ventricle can become enormously enlarged. Explain why this might lead to regurgitation of blood through the mitral valve (blood flowing from the ventricle back into the left atrium) during ventricular systole?

With a stethoscope, Dr. Tong detects some wheezing and inspiratory rales and orders a chest X-ray. The X-ray films show a markedly enlarged left ventricle and a generalized haziness at the base of Leo's lungs suggesting the presence of fluid. How might Leo’s lung symptoms be related to the defective valve Why might Leo's left ventricle be enlarged?
