Which actions are functions of the circulatory system? Select four options.delivers nutrients to cellsbrings carbon dioxide to cells for useprotects the body from pathogensremoves waste materials from cellshelps cuts and wounds to heal

The circulatory system transports nutrients to cells and carries waste products away. It also supports the body's defenses by moving immune cells and helps wounds heal by delivering clotting components to the injury. Carbon dioxide is carried away from cells to the lungs for removal; it is not brought to cells for use, so choice B is incorrect.
