Travis drew a model shown to describe how the body’s organs and systems meet the needs of all the body’s cells. the numbered parts of the model have not been labeled. what system does box #3 represent? a) nervous system b) excretory system c) digestive system d) respiratory system

Actually it’s B, baboom bes

You don’t have to lie...

Explanation:

The respiratory system (1) allows cells to exchange carbon dioxide and oxygen. The digestive system (2) provides nutrients to cells. The excretory system eliminate wastes (other than carbon dioxide) that cells produce as a result of their metabolism.

photosynthesis makes the glucose that is used in cellular respiration to make atp. the glucose is then turned back into carbon dioxide, which is used in photosynthesis. while water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
