When does the human heart form in the human body?

Answer 1

it will take a babys heart 40 days or 6 weeks to develop it will go through a phase called looping. Then when the baby is born after its first breath the valves in vetro are closed and the ones used in life open. Since the baby is using its owns lungs now. The last valve should close about a week after birth, leaving the 4 other valves open.
Really early on one of the first things that is formed is the beginnings of its heart and circulatory system. Once it starts pumping the blood starts flowing.

Answer 2

It's hard to say exactly, but around the 3rd or 4th week in development, the human embryo undergoes a process called gastrulation. During this process, the cells of the embryo begin to specialize into different types of tissues, forming three layers.

During this process, a region called the cardiogenic region forms from one of the layers (called mesoderm) at the cranial end of the embryo (the end which will become the head). As development continues, this region will develop into the heart.
