5 0

Explanation:

Capillaries are thinnest blood vessels there are in human body or basically in any multicellular living creature. Capillaries are so thin, they are like a sheet made of cells. So there is nothing like capillaries which can introduce blood with the materials to be absorbed without letting both of them mix directly. Arteries and veins are too thick to carry out such exchange.
