Yes,because if one will stop a person will die.
The digestive system breaks down the food we eat into smaller nutrients which are moved throughout our bodies by the circulatory system. The respiratory system captures oxygen from the air and releases toxic carbon dioxide to the air.
The digestive system breaks down food to provide the components for cell maintainence, growth and homeostatsis. Respiration eliminates waste carbon dioxide from the system ( if it built up, the cells would die) and brings in oxygen which is used in cellular respiration to create energy.

respiratory system Circulatory system
The veins are found in the circulatory system.
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
Working together, the respiratory and circulatory systems perform gas exchange from the blood to the lungs. This exchange occurs at the alveoli.
respiratory, circular and digestive systems
The digestive system, respiratory system, circulatory system
they are all systems
The Digestive and the Respiratory Systems. Along the same Vein; here are another two: the Circulatory and the Capillary Systems.
Most jellyfish do not have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems.
Excretory is one of them im sure!
