What organ system is most closely connected to the respiratory system in earthworms?
Answer (2)
digestive system /////////////////////////////////////////////////////////////
The respiratory system in earthworms is closely linked to the circulatory system, as earthworms use their skin for gas exchange. Capillaries beneath the skin facilitate this process, allowing oxygen to enter the bloodstream and carbon dioxide to exit. Therefore, these two systems collaborate closely to support respiration in earthworms.
