How do the body’s systems work together to supply oxygen and remove carbon dioxide during cellular respiration?
The circulatory system transports oxygen directly to the cells, and the nervous system removes carbon dioxide.
The respiratory system transports oxygen directly to the cells, and the circulatory system removes carbon dioxide.
The respiratory system transports oxygen to the cells, and the digestive system excretes carbon dioxide as waste.
The circulatory system transports oxygen to the cells, and it returns carbon dioxide to the respiratory system for removal.
