What is the medical term for widening of a vessel?

What is the medical term for widening of a vessel?

Vasodilation, or the widening of blood vessels, happens naturally in your body when an increase in blood flow to tissues in your body is needed.

What is the widening of an artery called?

aneurysm, widening of an artery that develops from a weakness or destruction of the medial layer of the blood vessel.

What is the medical word for widening of the lumen of a blood vessel?

Vasodilation involves widening of a blood vessel lumen due to smooth muscle relaxation in the vessel wall and leads to increased blood flow. (vasodilatation) A state of increased caliber of the blood vessels.

What word describes an increase in the size of blood vessels?

Long-term autoregulation develops over weeks or months, and involves an increase in the size of existing blood vessels and an increase in the number of vessels in a specific area, a process called angiogenesis.

What is a viscosity in medical terms?

Medical Definition of viscosity 1 : the quality of being viscous especially : the property of resistance to flow in a fluid or semifluid. 2 : the ratio of the tangential frictional force per unit area to the velocity gradient perpendicular to the direction of flow of a liquid.

How do arteries expand?

Eat a heart-healthy diet

1. Add more good fats to your diet. Good fats are also called unsaturated fats.
2. Cut sources of saturated fat, such as fatty meat and dairy. Choose lean cuts of meat, and try eating more plant-based meals.
3. Eliminate artificial sources of trans fats.
4. Increase your fiber intake.
5. Cut back on sugar.

What is the ballooning of an artery called?

Interventional cardiologists perform angioplasty, which opens narrowed arteries. They use a long, thin tube called a catheter that has a small balloon on its tip. They inflate the balloon at the blockage site in the artery to flatten or compress the plaque against the artery wall.

Is a localized widening in an artery?

Aneurysm: A localized widening (dilation) of an artery, vein, or the heart.

Which blood vessels become progressively smaller and branch?

Arteries and arterioles The arteries branch into smaller and smaller vessels, eventually becoming very small vessels called arterioles. Arteries and arterioles have muscular walls that can adjust their diameter to increase or decrease blood flow to a particular part of the body.

Which of the following contribute to vessel growth and repair and may regulate blood flow through capillaries?

cells present in some continuous capillaries that lie external to the endothelium; have elongated tendrils that wrap around the capillary; they can contract and regulate blood flow through the capillaries; can differentiate into endothelial and smooth muscle cells and thus contribute to vessel growth and repair.

What causes viscosity?

Viscosity is a measure of the resistance of a fluid towards being deformed when under shear stress. Hence, it is also known as shear viscosity. It is caused by the attractive forces between molecules in close contact, and the friction between molecular chains.
