FUNCTIONS Supplies oxygen to the blood and eliminates carbon dioxide; also helps to regulate acid–base balance. Figure 1.8 Respiratory system. DEFINITION The organs that operate to remove wastes from the blood and to eliminate urine from the body. FUNCTIONS Removes various wastes from the blood; regulates the chemical composition, volume, and electrolyte balance of the blood; helps maintain the acid–base balance of the body. Figure 1.10 Urinary system. DEFINITION The heart and the vessels that carry blood or blood constituents (lymph) through the body. FUNCTIONS Transports respiratory gases, nutrients, wastes, and hormones; protects against disease and fluid loss; helps regulate body temperature and acid–base balance. Figure 1.9 Circulatory system
