|
Connective tissues have a free surface; epithelial tissues have no free surface.

|
|
Connective tissues cover and line; epithelial tissues bind.

Detailed explanation-1: -Epithelial tissue forms the covering of various organs and thus is the outermost tissue in most organs. Connective tissue is usually present underneath the epithelial tissue. Epithelial tissue is avascular with no blood supply.
Detailed explanation-2: -Epithelial and connective tissue are generally avascular, which means they lack a blood supply. While, Muscle and nervous tissue are vascular tissues, which means they have a strong blood supply.
Detailed explanation-3: -Epithelial tissues are nearly completely avascular. For instance, no blood vessels cross the basement membrane to enter the tissue, and nutrients must come by diffusion or absorption from underlying tissues or the surface. Many epithelial tissues are capable of rapidly replacing damaged and dead cells.
