Which shows the best connection between the digestive and excretory systems?
1the digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
2the digestive system rids the body of the cells’ waste and the excretory system fuels the cells.
3the digestive system does physical digestion while the excretory system carries out chemical digestion.
4the digestive system carries out chemical digestion while the excretory system does physical digestion.

1. The digestive system fuels the cells and excretory system rids the body of cell waste.

The digestive system breaks down the food into simple components like sugars which can be taken up by cells as a fuel to conduct cellular metabolism. Without digestive system food cannot be split into forms utilized by cells. During the process of respiration it is ensured that essential food components should be absorbed completely but this does not happen as some of the part cannot be absorbed by the cells which can be considered as  cellular waste and should be removed. This cellular waste is removed by the excretory system. Therefore, excretory system provides the rid from cellular waste.
