Functions of blood transport (transporting various substances)+ defense (protecting the body) Transport function of blood transport gases oxygen from lungs to tissues and co2 from tissues to lungs. Blood also transports nutrients these nutrients are transported from gi tract to cells, in the cells is where most of metabolic processes are happening and require nutrients, nutrients are also transported from storage sites to cells.
