E

Expert

Verified

Birds, similar to every vertebrate, contain a closed circulatory system. The heart is identical to the mammalian heart, containing four chambers (that is, two atria and two ventricles) and with no mixture of arterial blood and venous. (In mammals, though, the aorta curves down to left and in birds it curves down to right).
