Best Answer

(b) skin

In small wormlike animals, oxygen diffuses across the body surface and enters blood in the dense capillary mesh that lies just below the skin. Blood carries the oxygen to the body cells. Therefore, it picks up carbon dioxide and transports it to the skin capillaries where it diffuses out of the body.
