The muscular system helps animals move by contracting muscles. The excretory system, which includes the kidneys, ureters, bladder, and urethra, removes waste from the blood and stores and passes out urine. The nervous system is made up of the brain, spinal cord, nerves, and sense organs and controls body organs, coordinates muscle movement, and interprets information from the senses. The respiratory system provides oxygen to cells by breathing in oxygen through the nose into the lungs and breathing out carbon dioxide through the trachea and lungs.
