Blood Flow Through the Heart

Question 1

Right Side

Answer 1

right atrium -> right atrioventricular (tricuspid) valve -> right ventricle -> pulmonary semilunar valve -> pulmonary artery/pulmonary trunk -> branch into left and right pulmonary arteries taking blood to gas exchange tissue of lungs -> pulmonary veins -> left atrium

Question 2

Left Side

Answer 2

left atrium -> left atrioventricular (mitral) valve -> left ventricle -> aortic semilunar valve -> aorta (supplies all tissues except gas exchange tissues of lungs) -> superior vena cava (blood leaving head and neck tissue) -> inferior vena cava (blood leaving lower extremities) -> both lead back to the right atrium
