Specialized Eukaryotic Cells and Tissues
Arteries are constantly expanding and contracting due to the force of blood pumped from the heart, the “blood pressure”. One would expect the walls of arteries to be composed largely of:
|B||Connective tissue containing mainly collagen fibers.|
|C||Connective tissue containing mainly elastin fibers.|
Elastin fibers allow stretching, which clearly must take place in the walls of the arteries. Collagen confers strength and is not stretchable; cartilage is even harder and more unyielding. While a small amount muscle tissue may exist in the walls of arteries, it is not significant with regard to the question.
