Q. A tissue that lacks blood vessels and depends on underlying connective tissue for oxygen and nutrients is called:
Epithelial
Epithelial
Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue, along with connective tissue, muscle tissue and nervous tissue. Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body.
Epithelial layers contain no blood vessels, so they must receive nourishment via diffusion of substances from the underlying connective tissue, through the basement membrane. Cell junctions are well-employed in epithelial tissues.
Q. Epithelial tissue is characterized by each of these traits, except that ____________.
