Characteristics of Elastic Arteries
|
|
Largest arteries (ex:aorta, pulmonary trunk)
|
|
|
Thickest Tunica Media with increased elastic tissue
|
|
|
Can stretch & recoil (elastic rebound)
|
|
|
Reduces pressure differences between systole & Diastole
|
Explanation:
Detailed explanation-1: -The main function of the large elastic arteries is to serve as capacitance vessels that distend during systole and retract during diastole, pushing blood to the distal vessels.
Detailed explanation-2: -During systole, when new blood is entering the arteries, the artery walls stretch to accommodate the increase of pressure of the extra blood; during diastole, the walls return to normal because of their elastic properties.
