Final answer:
The circulatory and respiratory systems work together to supply oxygen to and remove waste from every cell. Oxygen, required for cellular respiration, is absorbed and circulated via blood, while carbon dioxide is expelled through the lungs.
Step-by-step explanation:
The circulatory and respiratory systems work in tandem to provide oxygen and nutrients to every cell while removing carbon dioxide and waste products. Oxygen absorbed by blood in the lungs through the respiratory process is circulated throughout the body by the blood vessels of the circulatory system. This enables aerobic cellular respiration, which is critical for energy production in the form of ATP.
Concurrently, carbon dioxide, a byproduct of cellular respiration, is transported back to the lungs via the circulatory system, where it is expelled from the body during exhalation. The process of gas exchange in the lungs is fundamental to the cooperation between these two systems, ensuring that every cell receives life-sustaining substances and discards toxic waste efficiently.
