Write in a paragraph (or using an arrows) to trace the blood flow from the superior vena cava, inferior vena cava and coronary sinus entering the heart to the pulmonary circulation and systemic circulation. Include in the pathway the heart chambers and heart valves as you trace the blood flow.

Describe the flow of blood through the heart and the blood vessels that branch from the heart, starting with the inferior and superior vena cavas.

Blood flowing from the vena cavae to the pulmonary trunk passes through what series of structures?Multiple ChoiceRight ventricle, pulmonary valve, right atrium, tricuspid valveRight ventricle, tricuspid valve, right atrium, pulmonary valveRight atrium, pulmonary valve, right ventricle, tricuspid valveRight atrium, tricuspid valve, right ventricle, pulmonary valve

Which of the following describes the path of a blood cell from the superior vena cava as it makes its way through the heart?Multiple choice question.right atrium --> right ventricle --> pulmonary artery --> lung --> pulmonary vein --> left atrium --> left ventricle --> aortaleft atrium --> left ventricle --> aorta --> pulmonary artery --> lung --> pulmonary vein --> right atrium --> right ventricleright atrium --> right ventricle --> pulmonary vein --> lung --> pulmonary artery --> aorta --> left atrium --> left ventricleleft atrium --> left ventricle --> aorta --> pulmonary vein --> lung --> pulmonary artery --> right atrium --> right ventricle

Blood from the superior and inferior vena cavae and the coronary sinus flow into the ______.Multiple choice question.right atriumsystemic circuitaortaleft atrium

Great Vessels of the Heart The great vessels of the heart include the aorta and pulmonary trunk that carry blood away from the heart and the inferior vena cava, superior vena cava and pulmonary veins that carry blood to the heart. • superior vena cava: drains blood from the ______________________________________ (regions of body) to empty into the superior region of the __________________________; contains no valves; • inferior vena cava: drains blood from the __________________________________________ (regions of body) to empty into the inferior region of the __________________________; contains single valve at its terminal end called the Eustachian valve; • pulmonary veins: 4 in number (right and left pairs); carry blood from the right and left lungs to drain into the ___________________________ to complete the pulmonary circuit; coloured red in models since they carry oxygenated blood (the only veins to do so); do not contain valves; • pulmonary trunk: also referred to as the main pulmonary artery; terminally divides into the right and left pulmonary arteries; carries deoxygenated blood from the _____________________________ to the lungs; coloured blue in models since it carries deoxygenated blood (the only arteries to do so); origin of pulmonary blood circuit; • aorta: carries blood from the _____________________________ of the heart to most parts of the body; origin of systemic blood circuit. answers only
