Question

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

Explanation:

Step1: Oxygenated blood flow

Oxygenated blood from the lungs is transported via the pulmonary veins to the left atrium. Then it moves to the left ventricle and is pumped out through the aorta for systemic circulation.

Step2: Deoxygenated blood flow

Deoxygenated blood from the body (via superior vena cava etc.) enters the right atrium, then goes to the right ventricle. It is pumped through the pulmonary arteries to the lungs for oxygenation.

Answer:

Top row (left atrium side): pulmonary veins, left ventricle, aorta
Bottom row (right ventricle side): right atrium, pulmonary arteries
