Capillaries
Capillaries
Nutrients diffuse to epithelium from underlying connective tissues, which have abundant blood vessels.
The capillaries allow diffusion of nutrients, waste, and oxygen through their walls, which are one cell thick. This diffusion allows transportation of nutrients and waste materials throughout the body.
Capillaries - The endometrium (epithelial lining/wall) of the capillaries is only one cell thick optimizing diffusion/osmosis between it and the tissue cells of the body
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.
