Question

How are new blood vessels formed?

Answer 1

Blood vessels:

1. Blood vessels are the components of the circulatory system that transport blood throughout the human body.
2. These vessels carry blood cells, nutrients, and oxygen to the body's tissues.
3. They also carry waste and carbon dioxide away from the tissues.
4. Blood vessels include a network of arteries, arterioles, capillaries, veins, and veins.

Formation of new blood vessels:

1. After the vascular network is formed, new blood vessels are formed through the division or sprouting of existing blood vessels.
2. This happens through a process called angiogenesis.
3. It is formed in the early stages of vasculogenesis.
4. Vasculogenesis is defined as the de novo formation of early vascular networks by differentiation, expansion, and coalescence of endothelial precursors.
