Question: Baker spends a long time listening to (auscultating) Caleb's heart. Where on the thoracic surface do you auscultate to the tricuspid, mitral (bicuspid), pulmonary, and aortic valves? Where do you think would be the best place to auscultate Caleb's abnormal heart sound? Explain your answer. Caleb has abnormal heart sounds that tipped the doctor off to a problem. Name the normal sounds of the heart and indicate what causes these sounds. In relation to the normal heart sounds, when would you expect to hear the abnormal sound Dr. Baker heard? Explain your answer. The defect in Caleb's heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Based on your understanding of blood pressure and resistance in the heart and great vessels, explain your answer to question 3a. When an echocardiogram is performed, the technician color-codes oxygenated blood (red) and deoxygenated blood (blue). Need Assignment Help?
