Explanation
The country that has developed the world's first 3D vascularized engineered heart is A: Israel.
The heart was developed by a team of researchers from Tel Aviv University led by Professor Tal Dvir in 2019. The 3D heart was created using a patient's own cells and biological materials, making it the first of its kind. The researchers used a specialized 3D printer to create the heart, which included blood vessels, ventricles, and chambers. While the heart is not yet functional, the development of this technology is a significant step forward in the field of organ transplantation and could one day lead to the creation of functional replacement organs.
