Three distinct layers of different tissue cells form the walls of blood vessels.
The outer most layer is connective tissue. The middle layer is smooth muscle. The inner wall is primarily composed of endothelial cells.
Which of the following groups of tissue types is found in blood vessels?
A. Connective, muscle, and nervous tissues
B. Muscle and nervous tissues
C. Connective, epithelial, and nervous tissues

I think it's C because I don't remember reading anything about there being muscle in blood vessels but i'm not positive. Can someone tell me if I'm right or wrong and if I'm wrong please help me figure out the right answer.
