Respitory/Circulatory System

Bengal tigers have a cardiovascular system. In a cardiovascular system the heart pumps blood into veins and arteries throughout the body. This blood is oxygenated which is helps these tigers breathe. They get their oxygen by either inhaling through their nose or mouth. It goes into their lungs. They exhale out carbon dioxide.
