The instructions for building the heart in an embryo are primarily located in the DNA within the cells of the embryo's mesoderm layer. This layer differentiates during development to form various structures, including the heart. Specific genes and signaling pathways, such as those involving the transcription factors NKX2-5 and GATA4, play crucial roles in heart development. Additionally, interactions with surrounding tissues help guide the proper formation and functioning of the heart.

The mesoderm layer of the stem cell provides instructions for building the heart. Mesoderm cells migrate to form the cardiac crescent, which eventually develops into the heart tube and further into the mature heart during embryonic development.
No. It is dead with no heartbeat. Actually it does, since an embryo has no heart. It is the mother's heart that is keeping the embryo alive. It isn't until it is a fetus until it has a heart. While its heart it not being fully used and has a hole in it that keeps it from fully working, its heart does beat.
The embryo needs a heart to establish a circulatory system that supplies oxygen and nutrients to developing tissues and organs. As the embryo grows, it requires a reliable way to transport essential substances and remove waste products, which the heart facilitates through blood circulation. This early development of the heart is crucial for overall growth and the proper functioning of the embryo. Without a functioning heart, the embryo would not survive beyond a certain stage of development.
