Verified step by step guidance

Step 1: Understand the structure and function of arteries. Arteries are blood vessels that carry blood away from the heart under high pressure. Their walls need to be strong yet flexible to accommodate the pulsatile flow of blood.

Step 2: Review the properties of elastic connective tissue. Elastic connective tissue contains a high concentration of elastic fibers, which allow tissues to stretch and recoil. This property is essential for arteries to expand during systole (heart contraction) and return to their original shape during diastole (heart relaxation).

Step 3: Compare the other options. Hyaline cartilage is found in areas like the nose and trachea, providing support but not elasticity. Dense regular connective tissue is strong and resists tension but lacks the ability to stretch and recoil. Adipose tissue is specialized for energy storage and insulation, not structural support or elasticity.

Step 4: Relate the function of elastic connective tissue to the walls of arteries. Elastic connective tissue is most abundant in the walls of arteries because it provides the necessary elasticity for the arteries to handle the pressure changes during the cardiac cycle.

Step 5: Conclude that elastic connective tissue is the correct answer based on its unique properties and its role in the structure of arterial walls.
