The capillaries are the only blood vessels without elastic tissue. This is so that the vessel walls are as thin as possible to reduce the diffusion distance (for gases and waste products). Veins do contain a layer of elastic tissue is their walls, but this is a very thin layer (when compared to arteries).

What are some connective tissue?
The three types are collagenous fibers, elastic fibers, and reticular fibers. Some examples of collagenous fibers are; tendons, skin, bone, teeth, hyaline cartilage, vitreous humor, the lens of the eye, cartilage, hair, and placenta. Some examples of elastic fibers are found in arteries, veins, and elastic cartilage. Some examples of reticular fibers are found in the meshwork of bone marrow, the liver, and lymphatic system.
What fibers surrounds the xylem and phloem?
The xylem and the phloem tissues are found in plants. Bast fibers surround the xylem and the phloem tissues in plants.

What is vascular system?
A plant's vascular system consists of vascular tissue. The vascular tissue is made up of xylem (transports water) and the phloem (transports sugars and other nutrients). Another component of the vascular system is the meristems: the vascular meristem and the cork cambium, both of which are sites of growth.
What is blood vascular system?
I've never heard the term "blood vascular system" used together like that, but the vascular system is the collection of vessels that move blood throughout the body.
