Detailed explanation-1: -Explanation: Capillaries are slender vessels that serve as a link between arteries and are one-celled thick vessels.

Detailed explanation-2: -Capillaries. Found near every living cell of the body. Microscopic – walls are one cell thick, this allows for the diffusion of substances into the cells from the capillaries and out of the cells into the capillaries.

Detailed explanation-3: -Capillaries contain two layers of cells: Endothelial cells are inside the capillary. They control the flow of fluid, nutrients and gases. Epithelial cells form a protective layer around the endothelial cells.

Detailed explanation-4: -Arterioles connect with even smaller blood vessels called capillaries. Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.
