Q

What are the 3 tunics that arteries and veins have and what are their functions?

A
  1. Tunica intima: inner coat that is smooth and allows blood to flow easily
  2. Tunica media: middle smooth muscle that is the thickest layer that allows it to stretch
  3. Tunica externa: outer layer that is connective tissue
