The first organ to develop during human embryonic development is the heart. This occurs very early in the process, even before the embryo has formed a complete body. The heart is crucial for transporting nutrients and oxygen throughout the growing embryo, ensuring its survival and development.
The development of the cardiovascular system is the first step in organogenesis, the process of organ formation. This intricate system, including the heart, blood vessels, and blood, plays a vital role in delivering essential resources to every part of the developing embryo.
While the heart is the first organ to develop, other organs start forming soon after, such as the brain and the nervous system.
