Vena cava → left atrium → right atrium → lungs → left ventricle → right ventricle → aorta Vena cava → left atrium → left ventricle → lungs → right atrium → right ventricle → aorta Vena cava → right atrium → left atrium → lungs → right ventricle → left ventricle → aorta Vena cava → right atrium → right ventricle → lungs → left atrium → left ventricle → aortaWhich of the following is the correct sequence of blood flow through pulmonary circulation? Group of answer choices Right atrium → right ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → right atrium Right atrium → right ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → right atrium Left atrium → left ventricle → pulmonary veins → pulmonary arteries → pulmonary capillaries (in lungs) → right atriumWhat is the correct sequence for flow of blood in the heart? o Superior vena cava → right ventricle > right atrium o Pulmonary vein > left atrium → bicuspid valve o Right atrium → mitral valve → right ventricle o Inferior vena cava > left atrium > left ventricle o Right ventricle > aortic semilunar valve → aorta

- Blood is pushed out of the heart through a large vessel, called the aorta. The aorta then divides into smaller and smaller blood vessels, eventually reaching vessels called capillaries. Capillaries are so small that oxygen and nutrients can diffuse across the vessel walls and into the tissues of the body, with CO2 and waste diffusing back into the blood. Let's say that the cross-sectional area of the aorta is 1 cm2 = 100 mm2. The blood pumps through the aorta at 100 mm/s but only through the capillaries at 1 mm/s. If each capillary has a cross-sectional area of 20 mm2, how many capillaries must there be in the body? Note: these numbers are not physiologically correct, but were chosen to make the math easier. The blood velocity through the aorta is closer to 300 mm/s. The capillaries have a total cross-sectional area of ~600,000 mm2 (6000 cm2), with a blood flow rate closer to 0.2 mm/s.In the given table, three of the anatomical and physiological terms are similar or related; one does not belong with the other three. Choose the term that does NOT belong in each of the following groups.

- The left ventricle wall is very thick since it must pump blood to the entire body along miles of resistant vessels. The right ventricle wall is comparatively thin since it pumps blood only to the lungs, which are right next to the heart. Which ventricle do you think pumps more blood and why?In the cardiovascular dynamics experiment (part 2), if the right beaker simulates the flow of blood to the systemic circuit of the body, what do the right valve and flow tube represent? Select one: aortic valve and pulmonary veins bicuspid valve and pulmonary veins aortic valve and aorta bicuspid valve and aortaWhich of the following is the correct circulatory sequence forblood to pass through part of the heart?a. R. atrium → right AV valve → R. ventricle → pulmonarysemilunar valveb. R. atrium → left AV valve → R. ventricle → pulmonarysemilunar valvec.
