Textbook Question
Chapter 8, Problem 2AWK
When a coronary artery bypass graft (CABG) is performed, the vessels used for the bypass grafts are usually veins taken from the patient's legs. Over time the grafted veins take on many of the characteristics of arteries; that is, they become thicker and stiffer. What might this suggest about the possible cause(s) of the structural differences between arteries and veins? Hypothesize what might happen if you took a section of artery and implanted it into a vein.

Why do arteries have thick walls of muscle and elastic fibers?
a. to give more area for cholesterol to deposit
b. strength and ability to expand and contract during heartbeats
c. to allow blood to flow in both directions
When it comes to arteries and veins, do veins have?
a) a tunica media that is missing in arteries
b) thicker walls than arteries
