carbon dioxide and oxygen
Material moves from the respiratory system to the circulatory system by diffusing across a membrane in the air sacks called alveoli.
epiglottis
The respiratory system brings in oxygen from the air, which is used by cells in the process of producing energy in the form of adenosine triphosphate (ATP). The circulatory system then transports this oxygen through the blood to the cells where it can be used in cellular respiration to generate energy.
The respiratory system is the system that handles breathing.
