Final answer:
Conducting arteries have two layers of elastic tissue called internal and external elastic membranes.
Step-by-step explanation:
In larger arteries, there are two layers of elastic tissue called the internal and external elastic membranes. The internal elastic membrane is located at the boundary between the tunica intima and the tunica media, providing structure and allowing the artery to stretch. The external elastic membrane separates the tunica media from the tunica externa.
