allows blood to flow directly from the right atrium into the left atrium to bypass pulmonary circulation - foramen ovale carries blood from the umbilical vein to inferior vena cava; allows some blood to bypass the liver - ductus venosus atrial contraction; systole; p wave - atrial depolarization max volume of air that can be exhaled following maximal inhalation - vital capacity allows blood in pulmonary artery to flow directly into the descending aorta to bypass the pulmonary circulation ...

UTA 5315 Advanced Pathophysiology Summer Test 3 Questions and Answers Rated A+ Mitral Valve Stenosis - Characterized by NARROWING of mitral valve - Normal is 4-6 cm -Narrowed is less than 2.5 cm - Caused by RHEUMATIC FEVER -More common in WOMEN -Oxygenated blood comes back into heart into the left atrium and down through the mitral valve to the left ventricle - Complex: Stenosis leads to volume/pressure in left atrium, which results in atrial hypertrophy/dilation, which increases press...
