Visit this site (http://openstaxcollege.org/l/heartvalve) to observe an echocardiogram of actual heart valves opening and closing. Although much of the heart has been removed from this gif loop so the chordae tendineae are not visible, why is their presence more critical for the atrioventricular valves (tricuspid and mitral) than the semilunar (aortic and pulmonary) valves?
Figure 40.11 Which of the following statements about the heart is false? The mitral valve separates the left ventricle from the left atrium. Blood travels through the bicuspid valve to the left atrium. Both the aortic and the pulmonary valves are semilunar valves. The mitral valve is an atrioventricular valve.
The flaps of the atrioventricular valves are kept pointed in the direction of blood flow by papillary muscles and chordae tendineae papillary muscles and moderator band chordae tendineae ad pectinate muscles chordae tendineae and trabeculae carneae
