Please note: This is a companion version & not the original book. Book Preview: #1 Health is not simply the absence of disease. It is an active state. Your body has five health defense systems: angiogenesis, regeneration, the microbiome, DNA protection, and immunity. They are responsible for maintaining your health and resisting the regular hazards you face as part of ordinary life. #2 The body has a defense system that keeps microscopic cancers small by starving them of the blood supply and nutrients they would need to grow. This defense system is called angiogenesis, and it is at the heart of how angiogenesis defends health by keeping us in a state called homeostasis. #3 The smallest blood vessels are called capillaries, and they are the final link in the chain of the blood vessel delivery system to your cells. They are located within two hundred micrometers of every cell in the body. #4 Angiogenesis is the process of growing new blood vessels to replace those that have been damaged. It is triggered by hypoxia, or lowered oxygen levels, in wounded tissue. The endothelial cells that line your veins are ready to grow new blood vessels if the right growth factors are present.
