It keeps the body freshly supplied with oxygen and nutrients, while clearing away harmful waste matter.
 
The fetal heart evolves through several different stages inside the womb, first resembling a fish's heart, then a frog's, which has two chambers, then a snake's, with three, before finally adopting the four-chambered structure of the human heart.
