exists and is an alternate of . In biology, adaptation is the process by which an organism changes to become better suited to survive in their environment. It can also refer to a physical or genetic trait that helps an organism to be better suited to survive in their environment.
Angiogenesis is the physiological process through which new blood vessels form from pre-existing vessels. This is distinct from vasculogenesis, which is the de novo formation of endothelial cells from mesoderm cell precursors.owever, it is also a fundamental step in the transition of tumors from a benign state to a malignant one, leading to the use of angiogenesis inhibitors in the treatment of cancer.
Angiogenesis (angio'gen'esis) -- the growth of new blood vessels -- is an important natural process occurring in the body, both in health and in disease. Angiogenesis occurs in the healthy body for healing wounds and for restoring blood flow to tissues after injury or insult. Occurs when diseased cells and tissue produce abnormal amounts of angiogenic growth factors, overwhelming the effects of natural angiogenesis inhibitors. 2  In these conditions, new blood vessels grow and feed diseased tissues; the new vessels are abnormal and leaky and can destroy normal tissues.
