and the right and left atriums. The heart uses multiple valves‚ which are limited in their movement by the papillary muscle‚ whose function is to make sure that blood does not flow backwards. Blood is able to flow from the atria to the ventricles‚ but not in the reverse direction‚ by way of the mitral and tricuspid vales. The right side is controlled by the tricuspid valve and the left side is controlled by the mitral valve. The pulmonary valve keeps the blood flowing in a forward motion through the

Williams syndrome also recognized as Williams-Beuren syndrome is a genetic disorder caused by a deletion of more than twenty five genes from chromosome 7. Although Williams syndrome is often non-hereditary‚ the chances of the syndrome being passed on if an individual with Williams syndrome has a child are fifty percent. Individuals born with Williams syndrome often possess distinctive facial features which make the syndrome easily recognized. These features include wide spaces between their teeth

To inform my audience about the four major heart diseases. Introduction I. Heart disease is the leading cause of death in the United States for both men and women. My name is ______________ and today I will be talking to you about the four major heart diseases. These being Atrial fibrillation‚ Cardiomyopathy‚ Coronary heart disease‚ and Valvular heart disease. My research includes The Centers for Disease Control and Prevention‚ www.emedicinehealth.com and www.webmed.com. As a result

heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and take blood away‚ etc... Veins
