I think that the bottom of epithelial cells is closest to blood vessels (if one were to look at a flat 2D image. Endothelial cells similarly would have the top of the cell closest to blood vessels.
Epithelial cells are the lining cells. they are not a tissue. this is to be understood first. the outermost lining is known as the epithelial cell lining. it is provided its nutrition through diffusion- indirectly through blood. BUT they DO NOT have a blood vessel supply, since they are not an organ/tissue, just a cell lining.

No, skeletal muscle tissues are located in the skeletal muscles and not blood vessels. Blood vessels are usually made of smooth epithelial cell tissue and not more on muscle.
The lack of nutrients inside a cell compared to the blood vessel creates a concentration gradient between the blood vessel and the cell. Due to the lower concentration in the cell, the nutrients diffuse through the blood vessel wall and into the cell.

Epithelial cells make up the glands, and the tissues that line the surfaces of blood vessels and organs in the body.
The Blood Vessel Carries Useful Materials To The Cells And Tissues Of The Body.
It has only one flow of blood.
Glands
Via Diffusion across the EPITHELIAL CELL LININGS of the Alveoli.
A capillary is a blood vessel that is one cell thick for the absorption of nutrients and removal of wastes.
Why do you think that the blood cells stay in the blood vessels
