Current Question (ID: 14530)

Question:

The lumen of arteries gets _____ because _____ of _____

Options:

1. narrower, dissolution, fat, cholesterol and fibrous tissues.
2. narrower, deposition, fat, cholesterol and fibrous tissues.
3. wider, deposition, fat, cholesterol and fibrous tissues.
4. wider, dissolution, fat, cholesterol and fibrous tissues.

Solution:

Arteries are blood vessels that carry oxygen-rich blood away from the heart to various parts of the body. The walls of arteries are composed of three layers: the tunica intima, tunica media, and tunica adventitia. The innermost layer, the tunica intima, is composed of endothelial cells and a thin layer of connective tissue. The deposition of cholesterol, fat, and fibrous tissue in the tunica intima can lead to the formation of plaque, a condition known as atherosclerosis. Plaque narrows the lumen of the arteries, making it difficult for blood to flow through, and can increase the risk of heart disease and stroke.
