This chapter follows oxygen from the air into the cells and carbon dioxide back out. It covers respiratory organs across animal groups, the human respiratory tract, the pressure changes that move air in and out, lung volumes, gas exchange by diffusion, the carriage of O₂ and CO₂ in blood, the neural control of breathing, and a few common disorders.
