Organs perform specific functions within the body, such as the heart pumping blood, the lungs exchanging oxygen and carbon dioxide, and the liver filtering toxins. Blood carries oxygen, nutrients, and hormones to cells, and removes waste products. Plasma is the liquid component of blood that carries these substances. Bone marrow produces blood cells, including red blood cells, white blood cells, and platelets. Organ transport, such as the circulatory system, moves blood and other substances throughout the body to support the functions of various organs and tissues. **
