Science, Tech, Math › Science Biology Prefixes and Suffixes: angio- Share Flipboard Email Print Angiogenesis is the formation of new blood vessels. These malignant (cancerous) tumor cells are promoting angiogenesis by releasing angiogenic growth factor proteins that bind to endothelial cells in nearby blood vessels and encourage the growth of new blood vessels from the existing ones.

This word part is used when referring to a receptacle, vessel, shell, or container. Words Beginning With: (angio-) Angioblast (angio-blast): An angioblast is an embryonic cell that develops into blood cells and blood vessel endothelium. They originate in bone marrow and migrate to areas where blood vessel formation is needed. Angioblastoma (angio-blastoma): These tumors are composed of angioblasts that develop in the meninges of the brain and spinal cord. Angiocarditis (angio-card-itis): Angiocarditis is a medical condition characterized by inflammation of the heart and blood vessels. Angiocarp (angio-carp): This is a term for a plant with fruit that is partially or totally encased with a shell or husk. It is a type of seed-bearing plant or angioperm. Angioedema (angio-edema): Also known as giant hives, this condition is characterized by swelling in the deep layers of the skin that contain blood and lymph vessels. It is caused by fluid accumulation in body tissues and is commonly brought on by an allergic reaction. Swelling of the eyes, lips, hands, and feet are most common. Allergens that may cause angioedema include pollen, insect bites, medication, and certain types of food. Angiogenesis (angio-genesis): The formation and development of new blood vessels is called angiogenesis. New vessels are formed as the cells lining blood vessels, or endothelium, grow and migrate. Angiogenesis is important for blood vessel repair and growth. This process also plays a role in the development and spread of tumors, which rely on the blood supply for needed oxygen and nutrients. Angiogram (angio-gram): This is a medical X-ray exam of blood and lymph vessels, usually done to examine the blood flow in arteries and veins. This exam is commonly used to identify blockages or narrowing of the heart arteries. Angiography (angio - graphy): After injection of a radiopaque substance, the x-ray examination of vessels. Angioimmunoblastic (angio - immuno - blastic): This term refers to the things characterized by or related to lymph gland immunoblasts. Angiokinesis (angio-kinesis): Also called vasomotion, angiokinesis is the spontaneous movement or change in the tone of a blood vessel. It is caused by changes in smooth muscle as it dilates and contracts. Angiology (angio-logy): The study of blood and lymphatic vessels is called angiology. This field of study focuses on diseases of the cardiovascular system and the prevention and treatment of vascular and lymphatic diseases. Angiolysis (angio-lysis): Angiolysis refers to the destruction or dissolution of blood vessels as is seen in newborns after the umbilical cord is tied. Angioma (angi-oma): An angioma is a benign tumor that is composed mainly of blood vessels and lymphatic vessels. They can occur anywhere on the body and include different types such as spider and cherry angiomas. Angiomyogenesis (angio - myo - genesis): This is a medical term that refers to the regeneration of heart (myocardial) tissue. Angiopathy (angio-pathy): This term refers to any type of disease of the blood or lymph vessels. Cerebral amyloid angiopathy is a type of angiopathy characterized by the build up of protein deposits in brain blood vessels that can cause bleeding and stroke. Angiopathy caused by high levels of blood glucose is known as diabetic angiopathy. Angioplasty (angio-plasty): This is a medical procedure used to widen narrowed blood vessels. A catheter with a balloon tip is inserted into a clogged artery and the balloon is inflated to widen the narrowed space and improve blood flow. Angiorrhaphy (angio - rrhaphy): This is a surgical term referring to the suture repair of a vessel, typically a blood vessel. Angiorrhexis (angio - rrhexis): This term refers to the rupturing of a vessel, particularly a blood vessel. Angiosarcoma (angi-sarc-oma): This rare malignant cancer originates in blood vessel endothelium. Angiosarcoma can occur anywhere in the body but commonly occurs in tissues of the skin, breast, spleen, and liver. Angiosclerosis (angio-scler-osis): The stiffening or hardening of blood vessel walls is called angiosclerosis. Hardened arteries restrict blood flow to body tissues. This condition is also known as arteriosclerosis. Angioscope (angio-scope): An angioscope is a special type of microscope, or endoscope, used for examining the inside of capillary vessels. It is a valuable instrument for diagnosing vascular problems. Angiospasm (angio-spasm:) This serious condition is characterized by sudden blood vessels spasms due to high blood pressure. An angiospasm can cause a section of an artery to close partially or temporarily disrupting blood flow to organs or tissues. Angiosperm (angio-sperm): Also called flowering plants, angiosperms are seed producing plants. They are characterized by ovules (eggs) that are enclosed within an ovary. The ovules develop into seeds upon fertilization. Angiostenosis (angio - stenosis): This term refers to the narrowing of a vessel, typically a blood vessel. Angiostimulatory (angio - stimulatory): Angiostimulatory refers to the stimulation and growth of blood vessels. Angiotensin (angio-tensin): This neurotransmitter causes blood vessels to become narrow. Angiotensin substances help to control blood pressure by constricting blood vessels to reduce blood flow.
