- 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.arrow_forward_____ contraction drives blood through the systemic and pulmonary circuits; outside the heart, blood pressure is highest in the _____. a. Atrial; ventricles b. Atrial; atria c. Ventricular; arteries d. Ventricular; aortaarrow_forwardIn the systemic circuit, the hearts _______ half pumps blood to all body regions; then blood flows to the heart. a. left; deoxygenated; oxygenated b. right; deoxygenated; oxygenated c. left; oxygenated; deoxygenated d. right; oxygenated; deoxygenatedarrow_forward
- 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?arrow_forwardList the functions of the cardiovascular system.arrow_forwardWhy is resting heart rate somewhat slower than the 80–100 bpm set by the SA node? The AV bundle branches slow the heart rate down. Sympathetic fibers release norepinephrine to slow heart rate. The AV node slows the heart to an average between its own rate and that of the SA node. Parasympathetic effects dominate in a resting individualarrow_forward
