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

The answer is; right atrium, pulmonary arteries, pulmonary veins, left ventricle, aorta

Deoxygenated blood from the tissues flows into the heart through the vena cava vein. The blood is pumped by the right ventricle to the lungs through the pulmonary artery. The blood gets oxygenated in the lungs and flows back to the heart through the pulmonary vein. The heart (left ventricle) then pumps the oxygenated blood to tissues through the aorta.  

answer: accepted answer: aquatic animals use the oxygen dissolved in water to carry out respiration. since the amount of dissolved oxygen in water is low as compared to the amount of oxygen in the air, therefore the rate of breathing in aquatic animals is much faster than it is in terrestrial animals.
