Blood vessels are elastic in order to maintain the circulatory system. The vessels need to be able to stretch based on the force of the blood that is pumped through them. There are also receptors on blood vessels that control the diameter in order to shift blood to other parts of the body.
The second layer surrounding the lumen in blood vessels is the tunica media. It is composed of smooth muscle cells and elastic fibers, allowing it to contract and expand to regulate blood flow and pressure.
The connective tissue type found in the walls of large blood vessels and in ligaments supporting transitional epithelia is elastic connective tissue. This type of tissue is rich in elastin fibers, allowing it to provide flexibility and resilience, enabling blood vessels to stretch and recoil with blood flow. Additionally, it helps maintain the structural integrity of ligaments associated with transitional epithelium.
Capillaries
Capillaries are the smallest blood vessels.
Elastic fibers are primarily composed of a protein called elastin, which provides elasticity and resilience to tissues. They also contain microfibrils made of the protein fibrillin, which helps to organize elastin and maintain the structural integrity of elastic fibers. Together, these proteins allow elastic fibers to stretch and recoil, making them essential for the function of various tissues, such as skin, lungs, and blood vessels.

Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.

The body's most muscular and elastic blood vessels are the arteries. They have thick, muscular walls that allow them to withstand and regulate the high pressure of blood pumped from the heart. This muscularity also enables arteries to constrict and dilate, helping to control blood flow. Additionally, the elastic fibers in their walls help accommodate the surge of blood with each heartbeat.
The term Elastic Arteries usually refers to the ability of blood vessels to dilate and constrict freely.
Blood vessels are surrounded by very small circular muscles which contract and relax to allow blood vessels to constrict and dilate. The vessels also contain elastin which allows them to stretch.
Arteries carry blood away from the heart, veins carry blood back to the heart.
The tissue in blood vessels is called elastic tissue as it have to control the pressure in blood and have to contract and relax to create a specific pressure so that every organ should receive blood.
Veins and capillaries do not have an outer layer of elastic tissue. While arteries possess an elastic layer to help accommodate the high pressure of blood flow, veins have a thinner wall and rely on surrounding tissues and valves to assist with blood return to the heart. Capillaries, being the smallest blood vessels, consist only of a single layer of endothelial cells, lacking any elastic or muscular layers.
