Answer
Blood is responsible for transporting nutrients and toxins, defending the body against pathogens and blood loss, and regulating body certain functions
Work Step by Step
Transport – Blood is the primary way of transporting nutrients and oxygen throughout the body and transporting carbon dioxide and toxins out of the tissues of the body.
Defense – Blood is capable of defending the body against pathogens and blood loss. White blood cells create antibodies to disable certain pathogens. Blood is also capable of clotting to defend against excessive blood loss in the event of a cut.
Regulation – Blood regulates body homeostasis by controlling body heat by picking up heat from the muscles and transporting that heat around the body, controlling its own salt-water balance with plasma and maintaining the body’s acid-base balance.
