Study Notes
Development of the Vascular System
- The vascular system appears in the embryo during the third week of development.
Development of the Heart
- The heart starts pumping blood in human embryos around 3-4 weeks after fertilization.
Origins of Cardiac Progenitor Cells
- Cardiac progenitor cells are derived from the lateral plate mesoderm.
Cardiogenic Cells
- The first source for cardiogenic cells is known as the cardiogenic plate.
- The central portion of the cardiogenic area is initially located in the anterior medial region of the embryo.
Test your knowledge on the development of the heart in human embryos. Learn about the early stages of cardiac development, the formation of the vascular system, and the important milestones in the development of this vital organ.
