Each of the blood vessel layers is affected differently by the aging process.

Which would a nurse suspect is responsible for a patient's fibrosis?

A) Tunica intima
B) Tunica media
C) Tunica adventitia
D) Fibrosis is caused by an enlarged heart

A) Tunica intima

Explanation:

Fibrosis is the process of formation of extra fibrous connective tissue in the organ or tissue in a reaction process. This is because of the benign or pathological state. In terms of injury it is caused by the scarring and if the fibrosis takes place in a single layer of cells this is called as fibroma.

The fibrosis results in the break down of the tunica intima layer. This occurs due to break down of fibrin thrombi. The tunica intima is the innermost layer of the blood vessel like artery or vein. This layer is made up of single layer of endothelial cells and supported by the internal elastic lamina. The fibrosis of the tunica intima will affect the blood flow and will cause the rupture of the blood vessels.
