Question

place the parts of the circulatory system in the correct order to describe the flow of oxygenated and deoxygenated blood in the human body
aorta pulmonary veins left ventricle right atrium pulmonary arteries
oxygenated blood transport deoxygenated blood transport
lungs superior vena cava
left atrium right ventricle

Explanation:

For oxygenated blood flow: After the lungs oxygenate blood, it travels through pulmonary veins to the left atrium, then to the left ventricle, which pumps it out through the aorta to the body.
For deoxygenated blood flow: Deoxygenated blood returns via the superior vena cava to the right atrium, then moves to the right ventricle, which sends it through pulmonary arteries back to the lungs to be re-oxygenated.

Answer:

Oxygenated blood transport sequence (empty boxes, top to bottom):

1. pulmonary veins
2. left ventricle
3. aorta

Deoxygenated blood transport sequence (empty boxes, top to bottom):

1. right atrium
2. pulmonary arteries
