EPIDERMIS
The epidermis.
Vascular in this sense refers to blood supply. Your epidermis is avascular, which means it has no blood supply of it's own. Because arteries and veins run throughout your dermis, the dermis as a whole is considered a vascular region.
The cuticle of the skin is a transparent layer, so it does not have a color of its own. The color we see in our skin comes from the underlying layers of the epidermis, blood vessels, and melanin pigments.
The epidermis, which is the outermost layer of the skin, does not have its own blood supply. Instead, it receives nutrients and oxygen through diffusion from the underlying dermis. Similarly, the subcutaneous connective tissue, also known as the hypodermis, is not directly vascularized with blood vessels.

the process through which the tumor supports its growth by creating its own blood supply is called angiogenesis
The medical term for tissues without their own blood supply is avascular tissue. These tissues rely on diffusion to obtain nutrients and oxygen from nearby blood vessels. Examples include cartilage and cornea.
That has never come in to question as you cant "reserve" your own blood. Blood banks are open
No, but a good guess. They are called the coronaries.
Coronary arteries supply blood to the heart itself.
