C. capillaries

The exchange of materials between the blood and tissues occurs in the capillaries. Capillaries are tiny blood vessels that form a network to reach the body's tissues. Their walls are thin enough to allow oxygen, nutrients, and wastes such as carbon dioxide to pass through to and from each cell. This is where the blood releases oxygen and nutrients that then diffuse into the tissues, and at the same time, waste products from the tissues diffuse into the blood for removal from the body.
