All the blood that passes through the aorta, except the blood that flowsinto the coronary vessels, returns to the heart through the venae cavae.(Hint: The diameter of the aorta is 26 mm, and the diameter of avena cava is 32 mm.) Explain why the resistance to blood flow in theaorta is greater than the resistance to blood flow in the venae cavae.Because the resistances are different, explain why blood flow can bethe same.

A major advantage of a double circulation is thata. blood can be pumped to the upper portions of the body by onecircuit and to the lower portions of the body by the other circuit.b. each circuit can pump blood at a different pressure to optimize thefunction of each.c. the oxygenated blood can mix with the deoxygenated blood beforebeing pumped to the tissues of the body.d. less energy is required to provide nutrients and oxygen to the tissuesof the body.e. All of the above are advantages of a double circulation.
