Vascular ontogeny within selected thoracoabdominal organs and the limbs.
The cardiovascular system is fundamental to life. Its vessels are the conduits for delivery of nutrients and oxygen to organs and the removal of wastes. During embryonic development, the vascular system is instrumental in the formation of organs. It contributes to the form and pattern of organs as diverse as the limbs and the gonads. Recent advances in molecular biology and genomics have afforded great insight to the control of vascular development at subcellular levels of organization. Nevertheless, there is little assembled information concerning the vascular development of the organ systems of the body. This paper begins by reviewing the modes of formation of embryonic blood vessels. This is followed by summaries of the ontogeny of the vasculature that supplies selected major thoracic and abdominal organs (heart, gut, liver, gonads, and kidney). The paper concludes with a description of the arterial development of the upper and lower extremities.
